Summary: When I first started playing this game, I thought maybe they figured it out.... how to make a MMORPG that's good and NOT WoW. While the game did not follow WoW....it was pretty bad, some time after lvl 20, I started realizing this is extremely repetitive. I did give it the benefit of the doubt and managed to get to level 80, at that point I couldn't wait to quit.
Summary: Guild Wars 2 starts out great. According to its pre-release 'manifesto,' it promises to be a 'different kind of MMO,' appealing to people who have hated the MMO genre in the past. That was my stand point - I never wanted to try another again. Their 'a new kind of mmo!' lured me in. And at first, it seemed like a genuine promise. GW2 is different in a few key ways - loot sharing, gathering node sharing.
Summary: Pay once and then play for free. I am not a big fan of MMO's. Only played EVE and SW TOR before this. I enjoyed EVE immensely, but it gets expensive real quick, and I was not willing to continue to pay for a subscription in TOR as I would fall asleep playing that game. With Guild Wars 2 I have found myself lost in game for hours without noticing. Can be a giant time sink. Gameplay is fantastic and intuitive, and I can play alone when I can't be bothered to join a group.
