I would have picked up Guilty Gear last night while I was at CC and traded along with another game. I have Sword of Mana and Sigma Star, but I haven't even played them yet, so I don't know if I'd like to keep them or not.
I also have Pac-Pix, Trace Memory (opened but mint) F-Zero GP Legends, Perfect Dark Zero for trade. I have lots of games from the CC deal as well for GBA, but again, I haven't played much of them and I'm at work, so I don't have a complete list.
I really want the Double Pack, but I can pick it up at my Kmart for 29.99 down the street if I wasn't so lazy.
