I'm playing this on 360. Graphics are a tad blurry at all times except when up close to people. Frame rate suffers occasionally, but not often.
Other than that, if you want a deep and very tough RPG ( essentially similar to any of the Gothics , and a tad like Two Worlds ) then this is the game. I'm thoroughly enjoying it, and if you liked any of the previous mentioned games, you'll love this.
The gameplay is very unforgiving and a serious challenge, but hit lvl 6 and you start getting your own back...big time.
Combat is engaging and fun and the voice acting is totally regionalised for the UK, with a bunch of gruff sounding northern and london accents that come out with some very funny lines. In fact, almost " Lock stock and two smoking barrels" gangster talk. Very good.
Anyway, ignore the naysayers who have given Risen naff reviews, if you like Gothic or Two Worlds then this is for you. If you really must have the top end graphics, then buy the PC version and make sure you have a rocking pc.
Alternately, buy the Xbox version, install it to the HD , & enjoy the game from your sofa on your 42 or 50 inch plasma, and screw the folks who moan, and just enjoy the spirit of the game.
