Is Sacred 2 online? If it is, is there a separate story to it or can you play co-op on the main story like in Borderlands?
Same story and world. The story depends on class and alignment (player who creates the session defines the story). Small changes but maybe you are into that. Where Sacred shines is in the gigantic world it offers and the amount of loot and customization. I think the co-op is 4 players, and it allows to do 2 players in the same console although the camera becomes crap since it doesn't split screen. It is easy to jump into. It also has a non-story mode where you have access to the world without worrying about the main story. It includes the sidequests and everything else so i have never used it. There is probably a good reason for it but I never found out what it was.
Another good point for Sacred 2 is the difficulty. You can keep increasing the difficulty (think diablo) and making your character godly with even stronger loot and skills. It is a good time waster if you are into this kind of game although it might become repetitive from time to time. --- http://www.xboxgamertag.com/gamercard/xXDelta%20ZeroXx/tempo/card.png
