Last week I played beta version of Star Wars: The Old Republic. It is now free to talk about it, so I'm talking
I played Zabrak bounty hunter named Tyrok. Bounty hunters are: Zabrak, Rattataki, Human and Cyborg (this last "species" is human with the electronical modifications. I think it doesn't deserve to be separate species, you could modify your human, and the developers could give us another species instead, but it's my opinion only and you don't have to agree with it).
Well, BH is good and easy to play solo and has good storyline. Of course if you wish to group with other players, you can. I tried also Sith Inquisitor. As a slave he must compete with other acolytes who attack him from time to time. But I think BH will be my choice when I will play the full version.
