Mike Geig joined Unity thirteen years ago as a screencaster and is now a principal developer advocate — a job with no sales quota, no marketing targets, and a single KPI: how happy the community is. He'll have flown close to 100,000 miles this year to find out, and he calls himself a game developer first and a Unity employee second. So we brought him the arguments Unity developers actually have: Godot overtaking Unity at the GMTK Jam after nine years, an engine that only started paying for itself in the last two years, the open-source fight he's been losing internally, the DOTS animation system that got cut, whether HDRP is really dying, and whether Unity AI can compete with a $200 Claude subscription. He'll never lie to us, he says — but he reserves the right to be wrong.🔹 Links: Mike on X: https://x.com/mikegeig Mike on LinkedIn: https://www.linkedin.com/in/mikegeig/ GMTK Game Jam 2026 engine stats: https://bsky.app/profile/gamemakerstoolkit.com/post/3mrmx5mi3mk24Yuri's Unity AI video: https://youtu.be/JsYYnVemozoAfter Effects MCP: https://github.com/Engine-Room-Games/after-effects-mcp🔹 Chapters:00:00 Intro02:23 What We've Been Playing10:44 100,000 Miles and a KPI Called Happiness24:18 Game Developer First, Unity Employee Second31:15 Two of Everything, Addressables, and Why Nothing Is a Two-Week Fix40:52 Engine Upgrades and the Lies We Tell Ourselves47:28 Godot Dethroned Unity (at Game Jams, Anyway)54:03 The Open Source Fight Mike Has Been Losing for Years01:01:06 The Engine Only Just Started Paying for Itself01:06:06 Digital Twins and Unity Studio: The Non-Game Side01:19:07 The Hundreds of Games You Didn't Know Unity Made01:31:43 DOTS Has No Animation System, So Don't Make a DOTS Game01:40:37 Thousands of Empty GameObjects, GetComponent, and Git Blame01:48:33 HDRP Isn't Dying, URP Is Becoming Universal01:55:26 Unity AI vs. a $200 Claude Subscription02:05:59 AI Witch Hunts, and Why Yuri Didn't Go Indie02:15:30 Mike's Unity Tips02:18:41 One Book, One Movie, One Game, and Pokémon GoEpisode URL: https://tech-debt.club/episodes/8-tdc-08-13-years-inside-unity-with-mike-geig

Daniel Mironov left Google to help start vgames in March 2020 — a games-only VC fund in a country with two dozen cybersecurity funds and none for games — roughly a month before the world locked down and mobile went vertical. Six years and nearly 50 investments later (SuperPlay and InnPlay Labs both went to Playtika, Candivore is still printing money with Match Masters), he's a partner at the fund and has just launched a $10M Indie Fund that hands PC and console developers project financing without taking a single frame of their IP. 🔹 Links: vgames: https://www.vgames.vc Indie Fund announcement: https://gamesbeat.com/vgames-raises-10m-fund-for-project-financing-for-indie-games-exclusive-interview/ 🔹 Chapters: 00:00 Intro 01:46 What We've Been Playing 09:57 vgames, or How to Start a Games Fund in March 2020 20:36 One in Fifty, and Why the Job Is Saying No 33:38 Show Me a Prototype, Not a Deck 47:28 What Turkish Founders Are Better At 53:05 What $3–4 Million Actually Buys 01:12:34 China, IP Deals, and the Platform That Never Came 01:20:17 The Palworld Question 01:29:36 The Indie Fund: Capital Without a Publisher 01:51:32 AI on Steam and the Jonathan Blow Exception

Ivan Murzak spent the early 2010s shipping Evil Cogs, a Limbo-style mobile platformer that hit 5 million downloads on Android by squeezing performance out of phones that had no business running it. A decade later, he's a Microsoft MVP maintaining what's become the most-downloaded open-source Unity MCP server - the one anyone trying to get Claude, Cursor, or Copilot to actually do useful work inside the Unity editor probably ends up using.🔹 Links:Unity MCP: https://github.com/IvanMurzak/Unity-MCPIvan's YouTube: https://www.youtube.com/@Ivan_Murzak_Dev🔹 Chapters:00:00 Intro03:22 What We've Been Playing13:49 Evil Cogs: 5M Downloads and Limbo by Accident44:09 Why You Shouldn't Give Your Game to Your Mom01:06:17 Building the Most-Downloaded Unity MCP01:20:05 The MCP Zoo and Why CLI Is Winning01:48:46 Reflection All the Way Down02:04:11 Does the CS Degree Still Make Sense?Episode URL: https://tech-debt.club/episodes/6-tdc-06-from-indie-game-dev-to-top-unity-mcp-with-ivan-murzak

Andreas Gielov spent three years helping run Brackeys, one of the most influential Unity YouTube channels of all time. After Brackeys stopped producing Unity content, he went on to manage a string of game development YouTubers before joining Sirenix — the team behind Odin Inspector and the upcoming UI library Pangui — as VP of Marketing.We talk about what actually makes a game dev YouTube channel work, why advocate-driven marketing beats paid ads in niche markets, and why Sirenix has been quietly building Pangui for five years before letting anyone see it. Along the way: the tech stack is bloated, your in-house Unity UI framework probably shouldn't exist, and Jonathan Blow gets brought up (again).Chapters00:00 Inside Brackeys and the Reality of Game Dev YouTube48:18 Buying 70 Odin Licenses (And What Happened Next)54:23 Why Odin Worked, and What Pangui Actually Is01:02:51 Five Years of Silence on Pangui01:08:21 Rebuilding UI From Zero01:14:36 Open Source, AI, and Why You Shouldn't Build Your Own UIEpisode URL: https://tech-debt.club/episodes/5-tdc-05-from-brackeys-to-pangui-with-andreas-gielov

Lior Hadashian, co-founder and CTO of Gavra Games, joins Yuri and Amit to talk about building and shipping Warriors Rise to Glory — a turn-based gladiator fighting game inspired by a goofy Flash game from the internet's ugly years. What followed was five years of bootstrap chaos: a Bilibili influencer blowing up the game overnight, a Chinese localization done in one week, a main font that turned out to be stolen, two appearances on Israeli Shark Tank, and a mobile pivot that never happened.They also go deep on the realities of indie investment — what it actually means to raise money, why turning down $130k on live television was the right call, and what "alive but not kicking" looks like for a studio winding down.The back half gets technical: Unity version upgrades and why they break in exactly three places every time, Google's ongoing war with Unity Package Manager, and Amit's experience upgrading a 4-year production project to Unity 6.3.Lior is working on something new. He won't say what it is. He's on Unity 6.4.Topics covered:Warriors Rise to Glory — the game, the inspiration, the Venn diagram problem of turn-based fighting gamesLaunching on Steam without localization infrastructure, then scrambling to add 10 languagesHow a BiliBili influencer caused a Chinese localization crisis in week one of early accessThe font that was illegal (and why you can't just pay for it)Israeli Shark Tank — declining the first deal, coming back with receipts, and closing the secondWhat $40k of initial investment and $257k in gross revenue actually gets youWhy going mobile fell apart (the chicken-and-egg problem of mobile talent and capital)Unity upgrade pain: asset bundles, TextMesh Pro, shaders, and Google's UPM situationSwap Heroes — Amit's game, go download it, leave a review (constructive preferred)"Your brain is the product"Time Codes:00:17 – Cold open: what are you playing08:32 – Meet Lior / Warriors Rise to Glory14:33 – The Venn diagram problem15:13 – Localization: the full saga (BiliBili, 20% refunds, one week, illegal font)37:36 – Shark Tank: twice, one rejection, one deal47:52 – The numbers, the aftermath, the pizza1:00:00 – Mobile, burnout, and the end of Gavra Games1:05:37 – Unity upgrades: what always breaks1:15:23 – What's nextGuest: Lior HadashianEpisode URL: https://tech-debt.club/episodes/4-tdc-04-from-shark-tank-to-steam-with-lior-hadashian

Karlo Kilayko has been making games since before most of us knew what a game engine was - literally. From programming a CD-ROM murder mystery in C with one reference book and no internet, to shipping 30 mobile games a year across 382 devices at THQ, to becoming one of Unity's earliest professional users, Karlo has lived through just about every era of this industry.We talk about what it was actually like to break into game dev in the 1980s, the brutal carrier-controlled mobile landscape before the iPhone rewrote the rules, and why the Nokia N-Gage might be worth more on eBay than you'd think. We also get into the conversation that doesn't go away: AI, what it can actually do for developers today, and the question nobody seems to have an answer for - where do juniors gain the foundational experience they need to use it effectively?The second half turns toward shipping - or more honestly, the reasons people don't. The core philosophy, borrowed from a Trip Hawkins one-liner: you make zero billion dollars on games you don't ship.We also cover object-oriented vs. data-oriented design, the game engine vs. game IDE distinction, clean code debates that get surprisingly personal, and how Unity's MCP limitations are affecting AI workflows right now.Chapters:00:00 - Introductions00:32 - What we're playing05:33 - Why people make things09:35 - Breaking into game dev in the 80s13:00 - Programming a CD-ROM murder mystery17:15 - Data-oriented design, then and now20:30 - ECS, composition, and Raylib22:00 - Being an early Unity user26:00 - Mobile games as business applications31:00 - The Unity runtime fee debacle34:00 - AI engines and the engine vs. IDE distinction38:00 - Unity, MCP, and AI workflows40:00 - AI amplifies what you already have43:00 - Clean code debate51:00 - Vim, terminals, and knowing the basics55:00 - COBOL and legacy job security1:03:00 - When designers use Cursor directly1:05:00 - THQ Wireless: 30 games, 382 devices1:09:00 - Nokia N-Gage and early mobile multiplayer1:13:00 - Creative QA: elevators and microwaves1:16:00 - Carriers, control, and the iPhone1:19:00 - Better done than perfect1:27:00 - The 90/90 rule and shipping frameworks1:33:00 - Wrap-upGuest:Karlo Kilayko - game developer and producer.Episode URL: https://tech-debt.club/episodes/3-tdc-3-40-years-of-shipping-games-with-karlo-kilayko

In this episode, Yuri Sokolov and Amit Netanel talk about what AI is actually changing in software and game development - and what it is not. They dig into the difference between productive and destructive AI workflows, why experience still matters when using LLMs, and why most developers and companies still struggle with architecture, tooling, and learning the right lessons at the right time.They also get into Unity’s recent AI announcements, MCP servers, world models like Genie 3, startup culture versus corporate bureaucracy, the culture around bad practices in gamedev, and how social media shapes shallow technical opinions. Toward the end, they circle back to Bethesda-style engine hacks, AI hype in the industry, and whether AI is really replacing developers or just reshaping the work.Chapters:00:00 - Will AI take our jobs?00:15 - Waiting on AI01:45 - Good vs bad AI workflows04:02 - AI for real dev work06:13 - CAD and deterministic thinking09:54 - Players want fun12:46 - DI vs singletons14:13 - Learning architecture through pain18:56 - Startup vs enterprise culture21:00 - Growing company pains23:48 - Low barrier engineering culture30:11 - LinkedIn brain rot32:13 - Bad gamedev takes36:49 - Clickbait and shallow opinions39:32 - Focus and empty calories44:00 - Unity AI announcements45:26 - Genie 3 and AI hype50:19 - Unity MCP55:31 - AI for investors58:13 - Where AI actually helps1:00:25 - Extreme AI game jam1:02:51 - AI amplifies skill1:05:29 - Prompting with constraints1:08:43 - Debugging with AI1:10:29 - Fallout 3 train hat1:12:55 - Bethesda engine hacks1:15:18 - Building while AI works1:17:59 - AI changes the work1:19:01 - Is programming dead?1:21:51 - Build vs buy1:23:31 - SaaS needs real value1:26:27 - Losing knowledge to AI1:28:07 - Seniors using AI badly1:30:24 - Could AI replace devs?1:31:50 - Layoffs and AI optics1:33:35 - Unity promises1:35:47 - Wrap-upEpisode URL: https://tech-debt.club/episodes/2-tdc-2-has-ai-killed-game-dev-or-are-you-just-lazy
