Doom 3 isnt scary. It just makes you jump coz things fly out of vents, round corners etc.
FEAR actually made me scared in places (with the lights off and sound turned up). When you get near to certain things, like Bloodywolf said, your HUD starts getting interference and you hear things. Personally the bit that scared the shit out of me the most was when you go to a ladder in a deserted part of the start of a level, you activate the ladder to climb down and as your character turns around the little girl is right behind you...that made me shout out loud!
In my opinion, FEAR has a scary atmosphere all the way through...that girl is everywhere. Doom just throws enemies at you all over the shop and the whole darkness thing just pisses me off coz you cant see fuck all!! That much time spent in complete darkness and your eyes would start to adjust, NOT IN DOOM!! The thing that makes FEAR better is the fact that its in a recognisable setting, not on Mars.
Plus, then youve got the brilliant slo-mo feature, melee attacks and absolutely fantastic enemy AI. The AI in FEAR is comparable to the AI in Halo 1&2 on Legendary difficulty...its like youre actually fighting against intelligent enemies, ones that work together, not ones that just stand there while their mate next to them gets his head blown off.
