Best MMO on the market!!
The story lines are the strongest point here though. Most MMOs, you just glance through the text, and get to the smashing things because that's what its all about. This one though, you want to listen to everything going on, and then think about your responses. The dark side/light side answers could be a little clearer, but there's an option to see which way to answer if you want.
Character customization is best I've seen outside of City of Heroes, and that was really only because of the costumes. You can have an ugly, scarred, fat ass, tatooed, Bounty Hunter Zabrak(think horns) if that's your cup of tea. This is far deeper than you'll find even in WoW after all the years its been out.
Combat in pvp can be hectic just like in any MMO. Let's face it, in pvp online, no one is going to stand in one place like in pve, but its still great. The one gripe would be letting you choose which specific warzone you want to do.
My only complaint at this point would be that the classes on each side are pretty much mirrors of each other. I know that now, because of WoW(and its a fact) we're going to have to tolerate this in just about all MMOs now(thanks a lot Arenas). While I don't see a patch eventually changing the classes up some, maybe in the first eventual expansion can get a little variety in classes between the factions. This still isn't a big enough negative though to take away from all the good.
Bottom line, if your an MMO fan, and your as bored and sick to death of WoW as I became after WOTLK, do yourself a favor and give this a try. About the only way you'll be disappointed is if you can't get over your crush on WoW, and really, this game isn't targeted to you then anyways.
