playing downloaded pc games?
 

I have windows xp pro,and have used this p2p site for about a week.This place is killer to try out different downloads.However the only try out area I cant figure out ,is after downloading a shared game,how or where do you play it in my system?I have listened to muisc and watched video clips from here with no problem!I have checked out the read before you post and cant find anything.On the same note please be eeasy with the complicating lingo.I am computer dumb!Thanks
