During the semester I had it. Group projects were blowing, I was the only one doing work in one of them. Finally I had a weekend to myself, my roomies X-box, and a bunch of ripped games on it.
Punisher, dear god punisher.
I got to slice people like fish, blow em up, killem in various ways (quick kill was Godly). By the time my friends got back the found me sitting in my boxers, camping a spawn point, and had bodies stacked on either side of me. (I also had a million extra points by this time). After all was said and done I felt relaxed and vindicated.
Most people say violent games are harmful, in this case it kept several people very much alive for being absolute fuckhats.
