Getting sub 200ms on something like this benchmark is fairly easy [1]. While waiting for the color to change is different than processing a game like dota2 or sc2 a 200ms limit isn't too unreasonable to me.

I would love to see these AIs get handicapped even more like a full second and really force them to out think humans.
