I played pre-launch and at launch, its not bad for an MMO but it failed to the expectations of many of us who payed for it in advance (hence why its now free to play). I shelled out like 70 bucks for the pre order too, and I'm broke.
Lots of us were expecting an experience like Knights of the Old Republic 1 & 2. Instead we got a Star Wars themed World of Warcraft (fuckin' hate that game) with the dialogue aspect of KotOR. Its still good though.
