get a ton of friends....tables...drinks....xbox 360 linkage....sleeping bags....empty room with good ventilation....have fun.
I use to have lan parties once a year with my close friends...none of us were hardcore or anything...but damn playing dota, CS 1.6, any FPS is much funner with friends..
Now I can't do that **** anymore so instead we get together and go the the local lan center lol.
