My comp can handle Crysis on ultra with no complaints so doom is no issue for me, and I've been on a console since i was 4+-, pc is actually new to me.

I did enjoy the Half lifes, don't wont to give the impression that I don't. They are just too overrated, the only different thing in them is the gravity gun, other than that is basically just a generic FPS, but its enjoyable.

Oh and I adore most horror games, even though they don't scare me.
