I love the UFC 2009 Undisputed Demo.
Probably it is because of the graphics, the atmosphere, the animations, the detail of the characters, the realism... but this is one of those demos that can keep me playing for hours.
I don't know if I will buy the game. I didn't have so many games still to play and so few time available, I would consider buying it. However, the demo was a great surprise.
