I've been playing it since open beta and I'm in the 3rd zone right now (Blue Mountain). Most people either love the game or hate it and are waiting for GW2.
I love the game. My favorite things about it
- Best questing/PVE I've ever seen in an MMO. I haven't played through GW2's dynamic events so I can't compare but until it comes out, I don't think there's a better PVE experience on the market.
- Well written dialogue and cut scenes. SWTOR I'd hit escape during the cut scenes because they were so damn dry. Here they actually have witty writing and it contributes to the atmosphere instead of just telling you why you have to do a quest.
- The whole horror atmosphere is pretty effective. Ambient sounds, the way missions are laid out, NPC dialogue all contribute to a feeling of dread. I rolled an Illuminati and the first faction mission had me going into a pitch black parking garage. I find a helmet light that I'm supposed to use to light the way so I don't run into zombies. After a couple floors, the helmet light burns out and the only way I can see is by chucking flares that illuminate a small area. Another mission had me investigating a haunted house. Halfway through the door suddenly shut and the house tried to gas me to death.
- Real World setting. After a decade of MMO's based on elves or spaceships, it's refreshing to see things like cellphones, cars, computers, NPC's talking about Google and Youtube, etc. You walk through London and you see a coffee shop, record store, a nightclub, clothing store, etc
- It's a mature MMO. It's refreshing to hear NPC's cuss every once in a while.
On the flip side, PVP is weak, there are still some bugs, and a few quests are so poorly designed it felt like they were bugged. But I think it's worth the money. Between this and GW2, I don't see a reason to play WOW anymore.
