I have just been reminded how much I want a Mario Annverary Collection, with all the major NES, GB, and SNES Mario games on it. This list basically:
-SMB
-SMB2
-SMB USA
-SMB3
-SML
-SML2
-SMW
-YI
For the 8-bit games, there could be an option to play the original 8-bit version, or the 16-bit version from SMAS (I'd also love to see them make a 16-bit SML). There could also be an option to play a dumbed down easy version of each game, or a beefed up hard version of each game (as id SMB2J could get any harder). Lastly, they'd have to have hidden games. Preferably really obscure ones.
Iknow this is off topic, but for some reason I'm in the mood to write game ideas.
