So far it has been an interesting experience.
There hasn't been much of a main storyline so far. You do errands for Jabba, Watto, or Imperials (or Rebels), but that's pretty much it.
What's really exciting is that you can actually feel like you're living a profession in a Star Wars galaxy. (Just like the title says!)
For example, I decided to become a bounty hunter who punches people with Teras Kasi, and to actually work as a Bounty Hunter you have to do the actual legwork. You have to track a quarry with a probe droid, move through the hyperspace lane, then hunt him down with seeker droids.
And all the items you require, you buy from other users. I was baffled at first for this lack of seller NPC, but it was pretty funny to visit a store ran by an another user once you get used to it. Really makes you feel there's an actual community in here.
I guess this game would've been more of a blast to play back then, many SW fans would've felt like they were living a dream.
