It was difficult to choose what to quote. The article is high-quality overall. If you like AI and/or FPSs, that is.

This is one that games have yet to tackle (among games I’ve played, anyway) but it’s a major annoyance of mine. A bad guy pins you down behind some cover and then just plinks away at your hiding spot. Endlessly. Even if you hold your position for five minutes, the AI will just drill away at you without ever worrying about running out of ammo. And when you finally DO get out and kill him, he has nine bullets. Maybe he shot at you for five minutes, or maybe you took him down in a surprise attack. Either way, you always kill him nine bullets short of empty.
