Well this is undoubtedly the best game I ever played. The summary above pushes it as an action Sci-Fi but it is actually much more than that. It has adventure and mystery elements as well as just plain fun elements (like a boat race) that make this game so special. There is no dullness here, no point in which you are not exited and most important the game constantly surprises you with new things.
The story is excellent with a truly epic ending(!) and the characters endearing. It is suitable for all ages and that really means it is fun to play for adults as well without losing any of its appeal. It will engage you with its humor and enthralling game play.
