Dumb was really a poor choice of words, I basically wanted to say that the rules were incredibly simple and even so you get this complex behavior that comes out of it.

I remember the first time I played HALO and the guys talked to each other, and it wasn't just random sound effects they actually did the thing they were talking about. If the Elite guy said to "flank him" they would try to flank you or whatever, it was very cool.
