Depends on what kind of game it is. If it's a Metroid, Fire Emblem, or DK title, for instance, I'd prefer 2D on handhelds and 3D left to the consoles. If it's Mario, Star Fox, or Zelda, I'd prefer 3D across the board.

3D... I don't play on 3D all the time but when I do... Its usually for an epic scene (Such as cutscenes)

2D for handhelds, plus whatever Super Mario 3D Land was.
and 3D for consoles.

Could not care less. I want them to make great games that look good. It can be 1D for all I care if they can make it fun.

I just wish they could increase the number of internal studios they have that pump out high quality innovative games. Nintendo makes some of the best games, but I always feel like I am waiting for the ones I want. I know personal problem, but I would love for them to increase the amount of Nintendo magic that is produced.

Yeah, I never liked any of the 2D Starfox games either.

They keep impressing me with 2D-3D games equally. I am just going to let them do what they want. I won't ask for any game, I am just going to play their games. They are the real deal!

everything has a limit, and it has been proven than the bigger the company the less quality products it produce!

2D Metroid, DK and Kirby. 3D Mario and Zelda.
