Xenoblade
Pandora's Tower
The Last Story
SSBB
No more heroes 1 and 2
Madworld
NEVER sonic and the secret rings, I'm only mentioning it because of how BAD it is.
Bit trip
Chocobo Dungeon
Resident Evil 4 (if you haven't played on something else)
Wii Music is fun to mess with, but not worth a buy
Phoenix Wright ports
Pokemon Rumble is AMAZING IMO, so good I got the 3ds one too
Tales of Symphonia 2 is ALRIGHT, it's better if you hadn't played the first to know how bad it is,
but then you won't know most of the characters.
Sonic Unleashed is awesome on day stages
Sonic colors is worth all of the retro uprisings money in terms of bringing back awesome gameplay.
If I find anything I forgot on my back ups HDD I'll post it here
