While the philosophy behind Brink “MP” and that of Perfect Dark 64 is very different (i.e., Brink doesn’t have “arena” isolated MP gaming per se), being able to assign different personalities to the bots in Perfect Dark was brilliant and something I still haven’t seen copied (equaled) by any other developer since.
My friends and I set up a “Peace Sim”, made him a Man of the Cloth in appearance, and had him run around punching/stunning everyone while stealing their guns. We also created a Dominatrix and gave her the “Kaze” (revenge) personality. The results were hysterical, and haven’t been repeated since.
Personalities in bots is very, very cool, and PD is the only game I can think of that offered such extensive options for it. I haven’t bought the 360 version…because who would I play it with?
