I just want to know if you like 2-D, 2.5-D, or 3-D and why?

2D because the games are usually better and the graphics are nicer.
And there's no such thing as 2.5D. If you mean like NSMB only like 5 games are like that.

-NSMB.
-Sonic Unleashed
-Sonic Rivals 1 and 2
-Super Smash Bros. Melee
-Super Smash Bros. Brawl
-Super Smash Bros.

If the game is 2.5-D it's got 3-D graphics but you can only move one way like 2-D.

Sonic Unleashed has 3D portions.
And youk now in 2D you can move in all directions (RPGs).

2D by far. Best games and series originated on 2D.

2D. Pokemon was built upon 2D and many other great pokemon franchises aswell.

Yeah, 2D iz dah best. Pokemans wouldn't exist the same way without it.

2-D was good like 15 years ago since sm64 2d isnt that great and u cant explore as much as you would like

^^Yeah, but better games have been made from 2D then 3D.

2D ftw, I've never played better games.
