oh and im lucky enough to own a PSP(convinced my parents to buy it for me even tho im hella grounded, lol) that thing is a stoners dream, you put videos, music, and video games all in one. i have the simpsons weed episode on it, the PSP episode of south park, hella music to trip out to, especially on the headphones, and dynasty warriors. I could really use a new game tho.

I want to get God of War i heard its amazing.
Diablo II anyone?

im probably forgetting lots
