Well, two beta weekends, actually.
I had the duty of play-testing the Star Wars: The Old Republic beta for two weekends, the second of which just concluded. All-told, I played over the course of about six days, probably 30-40 hours of actual in-game playtime.
Let me just start out by saying I've been incredibly jaded about this game since it was first announced, doubly so when I learned that LucasArts was shutting down my (formerly) beloved SWG in an attempt to drive players from that MMO to their new one: SWTOR.
