I had a look at the video now (comments are in german), and I have to say that I am really impressed by the graphics I have seen. Can't say much about gameplay, but animation, landscape and interface looks pretty cool. In the voiceover they say that the game runs absolutely smoothly on a Pentium 750 with 256Mb RAM and a Geforce 3. Controls are a lot like Diablo, and if the RPG system behind the game is a good one, Dungeon Siege will seriously kick ass :-)
