My understanding of this game is that it isn’t a “traditional” MMO such as EverQuest or WoW, but rather a single-player game, wrapped in a massive, multiplayer universe. You drive your own storyline by choosing dialogue options a la Mass Effect (another Bioware marvel) and can play the same class twice with vastly different effects.
Group up with others and as you interact with NPCs, you also influence your partner’s (or party’s) storyline.
Finally we get to see a Jedi in action!
