as someone else said if they did they'd not ever talk about it.
Hypothetical situation. if say... Patrick stewart played SW:TOR. if he posted here "yeah I play SW:TOR, my character is named "bob" and I play on ebon falcon.
He'd be getting a LOT of tells. and proably constant harassment
If Patrik Stewart did play Swtor, then his character would probably be a smuggler whose name is Picard and has the "Captain" title applied to his character name. I haven't seen any guy walking around with that name on the Bastion server yet lol. I wonder if Brent Spiner plays SWTOR lol?
