I'm concerned that SMG may be too easy, while SPM seems to be potentially quite confusing..."I have to switch to 3d mode to get round this, then 2d to show myself running along the background", er, ok.
But both look like they're good experiences. There's also a new Paper Mario trailer thereabouts. In the Galaxy clip, Mario's shown doing lots of different tasks, across the various globes, and it really gets you thinking when you first see that world tip, and he's running, with the enemies still chasing, around the circumference of the sphere! There are lots of different shapes, with spherical only being a single example, and the gameplay's actually actively revolving around the planetoids.
Anyway, both seem like cool titles to me, but what do you make of the footage(s) and what Nintendo looks to be trying to do? Are these games likely to spend long in your Wii?
