I'll add to this. I'm having a great time in this game also. In a couple days I will have been playing for 2 months and I'm still finding elements that keep it fresh and fun. I can see myself keeping my subscription active for a long time.
My favorite things at the moment are:
Healing FlashPoints as an Operative.
Watching all of the cut-scenes.
The Imperial Agent story line.
Planning the orange armor looks of all my alts.
Lots of fun stuff!
