If you want some ideas for new Mario video games:
-Mario Kart for Game Cube, "Single Dash": I'd want a new one for the sole purpose of reintroducing the jump.
-Super Mario Brothers 64: I really had wished Luigi could have been in the game. Then two people could have played and it would have been easier for someone not too good like myself (who took nine years to beat Super Mario 64).
-Super Mario for the Macintosh. A long time ago someone gave me a copy of an emulator and a ROM to run Super Mario RPG (and said it was legal since he owned both the Super Nintendo and the game, "loaning" them to me). That was a lot of fun, since I could customize the controls. I also found the battle style in that one (where you fight with different options and not by jumping on things) to be much easier than Super Mario 64. If they could make another one of those that I could run on the computer that would be great.
-Mario Teaches Chemistry. I'm taking chem right now and having a computer program for it would be great. I used to have Math Blaster, Carmen Sandiego, and other similar programs back in the day and now they don't have anything for hard subjects like chemistry or biology or calculus. I remember doing so many division problems on Math Blaster back in the day and it sure did help. (I still have the old computer I used to run it on--it's in its original box and I haven't powered it up in almost two years now)
