Oh don't worry about that. I plan on doing this on 32 GHz+ worth of horsepower.
And according to existing YouTube videos, you can run 2000 AI bots on a 4 GHz processor just fine (low graphics though), let alone 1000 and 1500 in specific. Based on this information, 32 GHz could theoretically power up to 16,000 AI bots in simultaneous play. I would really like to see how that would look in-game, and how well the game engine could handle it, etc. I think of this as a curious experiment to test the limits of the game and going into unexplored territories.
