I built a 3D game engine with AI before Opus 4.8 and learned a lot

A while back, before Opus 4.8 dropped, I gave myself a challenge: build a real 3D game engine from scratch with AI, and see how far I could actually push it. It was never meant to ship. No product, no users, no roadmap. Just me trying to learn what building with AI really feels like when you go deep on something genuinely hard. Three weeks later I had a working 3D engine. Plenty of it broke along the way, and I rewrote things more times than I'd like to admit. But that's exactly where the learning was. AI didn't hand me an engine. It handed me a thousand decisions I still had to make and understand myself. Posting a video of it here because this is what DevConnect is for: real things people build with AI, rough edges and all. Curious from anyone who's tried something similar: what's the hardest thing you've built with AI just to learn, not to ship?
