here is an idea..
you know when you watch a replay and your thinking.. hey wouldnt it be cool if i could join this fight back from the start as a new player and then play the same battle..
well...
would it be possible to play vs yourself in and endless ffa? that you keep spawning as a new com.. and the engine disregards orders for units that dont exist because you killed them? ie. a desynced game..
sort of like when you race vs ghosts on racing games.
so:
game 1 you send 100 fleas..
game 2 you kill the 100 fleas and the game then disregards all future orders for those fleas to move..
i think maybe the engine would need a rework?
