The F.E.A.R. games. People always say that the second and third games were no where near as scary as the first, and while I can agree to that (in the sense that F.E.A.R. 2 was the most ridiculous attempt to squeeze in a few moments of frontal nudity at the cost what most fans found scary), I never found the first game that scary either. The first few times anything happened It was kind of creepy, but by the end, the game was getting so predictable that I was just saying "Guy's gonna jump out of that, lights will flicker up there, little girl will walk across hallway in front of me, etc. etc."
What happened to games like Condemned and Blood, Monolith? While reboots can flop, I wouldn't mind a current-gen reboot of Blood. That sort of game has a lot of potential on today's market, as long as you don't do what you did with Blood 2 (shudders at the thought of boring gameplay, stupid ending, and flimsy weapons)
