#5 Doom 3 - [ PC ]
id Software spent years on Doom 3 and the results, while mixed, still put the game in the upper ranks of games being able to scare the crap out of you. With equal emphasis put on blasting demons and crawling around in dark hidey-holes, the demonic encounters took on a more nerve-wracking quality. The scare scenes undoubtedly led to many PC gamers having to replace their mouse because of "sweaty palm" damage. While the game may be shorter than we would have liked, it's hard to deny the scary charms of taking on demons and zombies in space. Because everything, and we mean everything, is better in space. Yes, you can quote us on that.
