A side-scrolling Mario game that's injected with new ideas and a fresh look.
An all-in-one Mario sports game that just puts the tennis, golf, soccer, etc. franchises under one umbrella. Mario and Sonic at the Tokyo games being given a good treatment. An exclusive Sonic game that's not Boom.
Animal Crossing should be a no-brainer, and a new Luigi's Mansion could be nice. I'm not getting my hopes up for a new Wonderful 101. Or Mother 3.
Any more new franchises would be appreciated.
