@ohjtbehaaave: It clearly only adds one tomb to the game. in other words you can completely ignore it and just play the base game and no miss anything.
@levolden: it's getting real old seeing people cry about why is this here on everything gamespot posts. You're free to not be here if you're not happy with their work.
@kalgert: That doesn't take away from what it would cost if you bought it retail. The artbooks are impressive collector's items. Whether or not you look at them doesn't bring this fact down.
I have the soulstone USB stick from D3's collector's. it is an amazing item.
