AA was pretty realistic, considering. It's just that nowadays it's OMFG U GOT HeADSHhOTg!!111 LOzR/CMPR/CHETR!!111
I remember the days when whenever said someone was cheating, the reply was that you COULDN'T cheat it America's Army. It's all gone to hell.
I do like FarCry though. The AI isn't that bad, and, the most important thing of all; it's REALLY fun, imo. Having virtually unlimited ways of taking out the bad guys, while having a game world that acts reasonably like you'd expect it to, is a great boost to gameplay for me. Lots of times I've spent ten minutes just scoping out the enemy, locating their trackers through my binoculars, and spending the next 30 minutes luring them away and taking them out one by one, or flanking the entire camp and destroying them from behind.
