Description
I started off with a simple goal: port the game Soldat to Typescript. I ended up not only with the game, but with a full system to train AI bots to play my own game, building a neural net to train new bot AIs from tens of thousands of simulated matches with different strategies. It also runs live all the time on my website and has a news dashboard and you can replay any game exactly. It all was a very fun way to dig into Fable's capabilities.The bill if I had done this with API billing? Nearly $2000.

Could you build this?
Partial Porting basic game mechanics to the browser is straightforward, but engineering a deterministic 32-bit float physics simulation engine and an automated neural network training pipeline from millions of replays requires specialized simulation and ML knowledge.
What it would actually take: The stack requires a strictly deterministic TypeScript/WASM game engine with custom fixed-point or strict IEEE-754 single-precision float math to guarantee bit-identical replays across platforms. Additionally, it demands a distributed headless simulation harness, replay storage, and an RL/imitation learning pipeline (PyTorch/ONNX) capable of ingesting state transitions and generating bot brains.
