I've been thinking a fun game would be a very simple 1v1 first person shooter where you play locally against a neural net AI whose only source of learning is playing you, and you can have it fight online against other player's AIs.

Whether that would actually be fun or not, I think NN AI in games is underutilized at the moment. Probably because running one is so much more CPU/GPU intensive than just some scripted actions for basically the same results.

Small NNs are very fast. This particular NN only has 4 inputs, 2 hidden, and 2 outputs. That's what, 12 multiplications per pass? If you can compress your input down to a few variables you don't need much computation. For an FPS you could probably get away with player coordinates and direction.

I've read that some game devs tried more advanced AIs in FPS games. And the players hated it because they thought it was cheating when it snuck up on them.

Not 1st person nor 1v1, but I've made a shooter back then where you play against several nn
