The cool thing to do on these forums is to bash The Old Republic, but I love the game. It plays like WoW, but with lightsabers, which I think is great, I never had an issue with MMO combat so that wasn't a problem for me. The biggest thing though, at least for me, was the fully voiced npc dialogue, coming straight from WoW, where I didn't even read the quests anymore, the dialogue was so much more engaging than a text box. Each class gets their own personal story too, the one I've been playing, the Sith Warrior, has a story line that makes you feel like a total badass.
You can play it for free up to lvl 15 now, and it's going free to play soon
