In some games - most famously Doom - entire multiplayer is based on exchanging just the inputs and the games on all connected computers are deterministic enough to provide same outcome on all of them.

I am one of the authors of Fire Fight game (1996-ish) and we pulled the same stunt. It was actually easy, we just had to build our own "random number generator" and fix all bugs with uninitialized memory :-)

I love Fire Fight! I got the demo on a PC Gamer disc when I was a kid and played it forever. And couple of years ago when I built a retro PC, it was one of the first games I loaded up :)
