if you check out the lineup shown in this E3, there are at least 10 games for which you'd a GC just for it:
Advance Wars: Under Fire - advance wars in 3D? come on. beatiful
Fire Emblem - Im in love with the GBA version of this game and in 3D. another must have.
The Legend of Zelda (no title yet) - watch the trailer and try to not cry of emotion (only for zelda fans
)
Megaman X: Command Missions: - Megaman in 3D in an RPG in anime. awesome.
Star Fox (no title yet) - another fox for GC but this time we're back in the vehicles like in the snes and n64 versions which are what made fox such a success instead of the terrestrial SF Adventures.
and then lots of other favorites like:
- Metroid Prime 2: Echoes
- Paper Mario 2
- Mario Tennis
- Pikmin 2 - sequel to the surprise hit
- Resident Evil 4
- Tales of Symphonia - my number one awaited game till I saw Link
- Viewtiful Joe 2
