Guild Wars 2 is pretty fun. It's great to buy once, and drop every once in awhile. All the top gear is cosmetic, so questing is for the materials to make the gear you want instead of the power of the gear. WvWvW is great, and I just got into PvP last weekend and had a blast. ArenaNet has streamlined many aspects of the game. As my buddy put it, it is fun to level and explore the game with one character, but after that it's pretty boring. So they have insta level 20 items and other items that grant you a single level, and all of them are easy to acquire.
WvWvW = World vs World vs World, where 3 servers face against each other in 4 different maps that can be switched between at will. There is Zerging with a big force, and then there is small group play where you can capture camps, or back capping camps.
