Like Ice Climber? Or Mach Rider? Or Balloon Fight?

Fzero, mother, jetforce gemini, killer instinct ( the last two being of rare...)

The Mother series!!! I would love to see all three games in the series remade on Wii U and released in English so that I can play them. I know there is a fan translation for Mother 3 but I would like to play them in order.

F-zero, but the option of killer instinct could be great!

I wouldn't mind seeing a new Balloon Fight game.
I reckon that could be good fun if done well.

Tiger-Heli
Much more better than Xevious and Twin Bee

StarTropics.

Just F-Zero for me. We need F-Zero.

project H.A.M.M.E.R - it was forgotten in the sense it was supposed to be launched on the wii, but it was scrapped in the end. would love to see this on the wii U.

f-zero
mother
golden sun
captain rainbow
sequel to disaster: day of crisis
the legendary starfy
joy mecha fight
fire emblem
killer instinct- would be good if nintendo bought the rights to that game from rareware
star tropics
custom robo
excitebike
geist

Mother....wish there was something they would/could do to bring that series back. (and over here)
Besides that, hope they'll do a 64-style Star Fox game for the Wii U at least, though 3DS is fine too. (style as in, not Adventures, or or Command....and never really played Assault, lol)

I've wanted to see a completely new batch of Game and Watch games for a long time now. The new controller could add to the franticness as you are simultaneously addressing things happening on the TV screen and the controller screen.

This.

They should start the cancelled Earthbound 64 project back up, give it updated graphics, finish it, and ultimately release it. That's a huge demand on my part and I doubt it would ever happen, but I can always dream. D:

I'd also be cool with another F-Zero game if it was as awesome as F-Zero X was.

Thats a good idea, maybe they could make a Game & watch party/mini-game compilation style game.
I also agree with misswliu81 about Captain Rainbow. That looked like an awesome Wii game. Also, maybe they could make a prequel to Xenoblade chronicles to explain some of the plot holes left at the end. Although, the game might play very differently if it was made to explain those plot holes.

Metroid.

I'd really love to see what Nintendo could do with a modern take on StarTropics.

The exite series is still around. F-Zero & Earthbound are gone though.

Metroid's around - see Other M. Same w/ Game & Watch. See DSi Ware games.

Hmm, series that has been forgotten? Oh! i got it, what about balloon kid or metal combat.

how about a new Shin oni ga shima or devil world

I'll go with missliu81 with this, for saying Project H.A.M.M.E.R.
and Mega Man Legends if Capcom ever wants to. (But lets face it, they gave up)
