I played Vanguard in beta, and I really wasn't that impressed with it. It feels, to me, like they've looked at all the other MMOs out there and copied bits without really thinking about how they fit together, or if they were any good in the first place.

Sure, PVP is cool, big guilds and economies are cool, and flying mounts are cool, but only when implemented well, and only when getting to that stage of the game is fun. If you have to do mindless, boring quests in a badly thought out, generic combat system to get to any decent level, then how many people are going to stick with it?
