My only purchases so far have been at Gamecrazy. When I got there, most of the good games were gone with only Gameboy stuff left. So, I decided to buy some of the stuff I've been putting off.
GB:
Wario Blast
Castlevania Legends
Donkey Kong
Bubble Bobble
Wario Land 2
GBC:
Metal Gear Solid
Mario Golf
SNES:
Filmation Presents "Happily Ever After"
PS:
Chocobo Racing (Complete)
Pretty happy with that stuff A) because it cost me $45 and B) there was still stuff I wanted like 4 days after the sale started.
