I ran out of space....so there is that. I really didnt have much. I had Metroid Prime Trilogy 7 gigs, Trine 2 1 gig, Windwaker 2gigs, Mario 64, Super Metroid, Metriod Fusion, Punchout nes, Kirby nes, Retro City Rampage wii, Bit Trip Runner, smb3, and updates, updates updates. I only had 3 gigs left, so I deleted some Game data I hadn't been using, and copied some stuff over to flash drive. Sometimes little things add up like a credit card bill. I could however fit 615 nes games on a cd and still have tons of space left over.
