First of all, this game is not as bad as a lot of reviewers make it out to be...
Graphically this game is not a top tier game, but they are not graphics that you see from ps2 or the original 360. I like to compare it to being a little lower than oblivion, but not by much. There are numerous times where I would stop and look in the horizon to check out the view.
The story and quests are good enough to keep you engaged, and the exploration is great. But then again, I'm also very stubborn when it a mob or mobs kill me and I never reach that one corner where there may be some good loot...I keep going back for more. :) So if you are like me you'll enjoy the exploration The sound is also good, especially the music which sets the tone for the game very well. Controls, there is something to be desired there, but for anyone who has played the Gothic series, you should be used to these types of controls.
All together, the game is good, but is not for everyone. If you enjoy western style RPGs that do not hold your hand and challenges the player, this game is for you, and you should definitely give Risen a go.
