I avoided 15 because it didn't seem like something I would be interested in. I didn't get too in to 13, but I was kinda meh about it from the start. All of those games tend to have characters that either go way overboard with stereotypes or just plain annoy me, and it seemed like 13 really didn't hold back on that. I love 14, though. It is the only MMO I've played that could replace WoW for me. I really, really enjoyed it. If they had an equivalent to WoW tokens, where I didn't have to pay for a monthly sub, I never would have gone back to WoW last year.
