Now that the demo of FFXIII is available for a while, there has been some feedback of it on the net. Visually, it looks amazing, but I'm not sure what the gameplay system is going to be like. We'll have to wait a while to get our hands on the demo and even longer for the game, but I'm definitely looking forward to this. It looks like they've tried quite a lot different with this one, hopefully it works.
