I picked up Killer 7 today for the GC. I've never played it but it looks great!
Won several items on ebay tonight as well:
Naruto: Rise of the Ninja (360) - Not a Naruto fan but heard the game was excellent.
Resident Evil 3: Nemesis (GC) - Decided to get all the RE games on the GC (just need 2 & 4 now).
Wild Arms 4 (PS2) - Just need 2 and 5 now
Spent ~$55 total. Maybe not the craziest deals in the world but I don't think I over paid for anything.
My collecting is about to take a back seat since there are 3 games coming out next month that I actually want to sit down and play through.
