I just wish they'd expand some of them. Some of their IPs have potential to brancho out into different genres.
F-Zero comes to mind right away. They have over 30 characters that they could use for a fighting/sandbox/adventure/action games.
Starfy and Kirby could very well be in a cross over.
Custom Robo is dead, but it has potential as well. A full fledged RPG perhaps?
Then 1080, Wave Race, and Excite. Their last games were all very nice. Excitebots Trick Racing is a BLAST to play, with some mechanics that are rarely, if ever seen in racing games.
Glory Of Heracles could return as well. Geist could be their own FPS franchise (is it theirs?). Eternal Darkness and Fatal Frame can fill a void for Mature Rated games in Nintendo hardware.
Its a little frustrating, because we get Zelda and Mario spin offs very often.
