All my stuff is modded, but I still mostly buy games. In the past I copied everything, but usually only played a game the one initial time I fired it up. I really can't stand 99% of games. I miss the NES era when Nintendo's nazi-like control on the industry resulted in mostly good game releases. Compare that to the shovelware on PS2 and Wii (and the overpriced, pretty but mindless HiDef games on PS3/360).
If I liked a game, I bought it. Now, I just test games via GameFly, and buy the good stuff. The modchips seem like a waste now (and too much of a hassle).
