Honestly. Why the smurf would you want to make Final Fantasy VII in 2D? That's quite possibly the worst idea I've ever read - it shall never get completed, nor will it even get close to coming off the ground. That's almost as stupid as the Ocarina of Time 2D.

And why would you want to make Advent Children into a 2D game? There's no chance anyone'd be able to pull that off correctly, unless your name is Square Enix, which I don't think it is.
