[citation][nom]anthropophaginian[/nom]Sounds good. I presume AI 'make' dynamic decisions, constantly reassessing their situation with elements of randomness. One of my favourite AIs is still the original FEAR. You think you have the upper hand sneaking around them, but sometimes they take a different route and even change their strategies when you reload from a save. Not something you can sit back and plough your way through.[/citation]
Agreed, FEAR had good AI.
I also agree on the definition of fair. If the enemy can't see you, they shouldn't know where you are (unless its based on noise). If they did see you, then lost sight of you, they shouldn't be able to follow you behind a wall, down a hallway, and through another corridor to where you pop-out next.
And agreed on the omniscient helicopters. Nothing kills a game better than the mandatory "shoot down the fast-moving, infinite-ammo carrying helicopter" level. But damn if it ain't a pre-requisite for almost every FPS game out there. I think I got at least 10 games installed on my computer with an omniscient helicopter level.
