I was at my friends house yesterday and he just built a new gaming computer and was able to play outlast on max settings and graphics and he also hooked up his computer to his 70 inch HDTV and started smoking. That game was the craziest game ever to play stoned, you get an andrenaline rush from playing and you'll be shaking xD But anyway if you ever get a chance playing outlast play it.
haha your friend sounds exactly like me. i beat outlast when it first came out. best true horror game i've played in a looooooong time. and i was stoned the whole time lolol i showed my friend it last weekend and he was literally a nervous wreck and begged me to stop playing. we got only an hour in and he couldn't stand it anymore. we went outside to smoke (its dark out at my house, no street lights) and every little sound he heard he jumped asking me "what the fuck was that?". then he proceeded to call me crazy for beating the entire game by myself with no lights on. Now whenever i see him he tells me how that game scarred him and he has nightmares now. great game!
