@Leshma Nosferato is VERY tempting with the atmosphere and scares and shit but the damn animations the monsters have are sooo bad and funny at the same time it kinda ruins the horror in the game.
Still I'll probably buy it.
I know, it is low budget game but has its (really) scary moments. Also, on hardest difficulty it's truly hard to beat and on top of that you have time limit to finish it because clock is ticking for those you have to save. I usually play all video games on hardest difficulty and beat them easily but this one seemed quite impossible for me.
Nosferatu is like a cheap copy of Undying. Undying has better story, better locations, better NPCs, monsters, pretty much everything but it's less scary than Wrath of Malachi.
Doom 3 can be scary, sometimes, in its own way.
F.E.A.R. isn't scary at all, at least not for me.
