I'm not too sure the demo sold me. The controls were a little more complicated than I would have preferred. And it was too short for me to get a real feel of what the full game will be like. Its great to watch the game in action...just not as fun playing it.
Downloaded the demo. It caught my interest, but I'm sure I won't get it until after Christmas (although it is on my Christmas list now.) I'm getting Gears 2 this week and if I buy myself anything else before December 25th it will be Fable 2.
