i have doom 3, and i run it on high quality graphics at 800 x 600 with shadows turned off (soon i can turn them on when i get my new graphics card =)!!!! but it is a very spooky game, i turned my lights off an di have surround sound on my pc and i i just about jumped out of my chir a good 8 times lol. i beat the game within like 1-2 weeks, i made it last because i paid $55 for it lol. i highly reccomend this game for those who want a good scary game!!!
