Have you seen this Wario Land: Shake It business? It's a pretty startling thing -- an honest-to-goodness home-console 2D platformer, complete with full-out traditional 2D cell animation. (By Production IG, no less!)
Now don't get me wrong. 2D games with 3D graphics -- like, say, Viewtiful Joe -- are all well and good. But man... it's always good to see some actual honest-to-goodness 2D game art back on one of the major systems. Relegating these kinds of games entirely to handhelds makes about as much sense to me as relegating traditional animation entirely to television. Sprite-based games can be so pretty... especially when they aren't being drawn for screens that are as wide as my thumb and as high res as your average calculator.
But now here's Nintendo, not only making a new game with 2D art, but actually putting some real money and effort behind how that art is made, by getting a proper animation studio to handle it. I, for one, am impressed. In fact, this is almost enough to make up for Mario Party 327: Mario Harder.
