People reviewing this game 1.0 should really think about what they're saying.
If its not your thing that's fine, just don't give bad reviews without any reasonable points, other than "same old" or "blizzard suck"
I got the expansion on release, and have been enjoying questing with my friends and exploring the new areas and dungeons, the graphics are good, the sound is amazing, and everything runs smooth, apart from a few instances of lag here and there, but that's understandable considering how many people are filling the servers up.
It definitely doesn't deserve to get a 1.0.. really.. the game is immense and so much detail has been put into it, walk around a few of the new areas and you'll see what i am talking about.
If you're tired of MMO's then i wouldn't recommend getting it, because yes there isn't much that revolutionizes, but there are many new things and experiences that make it worth getting.
