I beat the demo and found it challenging and fun. The camera controls were OK but this is an obvious console port and the keyboard controls are a little wonky. I with everything could be picked up by simply walking over them like gold. The number controls are a little tricky and remapping of keys would be a nice ability. Graphically this game is very pretty. Not a whole lot on character development but the first two dungeon siege titles aren't known for that either. For a click and kill it's passable. Is it worth the $40-50 probably not. I'm still keeping the pre-order because I'm a tough person to shop for birthday gift wise.
If it wasn't for that I'd be pursuing a review copy from GamersGate or waiting for it to drop in price.
