I've played loads of MMO's over the past 8 years on and off, and I would have to say my opinionated choice out of all of them would be for Everquest 2. I've played WoW and Runescape much longer than EQ2, yet still admit that it seems to be better than both of them. One main reason, is the community. I never run into immature unintelligent kids demanding free money or items, in fact everyone I've met is quite respectful and intelligent. People don't seem as snobby, especially in PVP. Some kids on runescape act as if they own the world just because they got a half decent pure with a full special bar, lol. EQ2 is nothing of the sense, actually you usually don't have time to talk, because EQ2 has the biggest spell animations and sprites of all MMO's. The graphics are stunning, the community is worthy, and the gameplay is fun with friends. If anyone wants to start a trial to see how it is, I will provide a link and we could also exchange names so I can get you started up in game.
