I saw video this week of a new game called Fez that is still in development. You can see the video here.
Watch only the first 40 seconds or so, and you'd be forgiven for thinking that there was absolutely nothing new or interesting about Fez. You'd be sorely wrong, though, but you'd be forgiven.
You see, Fez is a 2D vertical paltformer game much like the class NES games Kid Icarus or Metroid, but with bright colors and simple character design that makes it look like a cheap Mario clone from 1988. However, the truth is that the game isn't 2D at all. It's a 3D game wherein changing the camera's perspective shifts the gameworld into new combinations of 2D elements.
Make any sense? Doubtful. But if you watch the video, you'll see what I mean. It's pretty freakin' sweet. As soon as I saw it, I thought that it might be the kind of game that could get my brother to dust off his thumbs and pick up a game again for the first time since the SNES. Once games went 3D, he lost interest. Maybe experiments like this can get him back into the fold.
