I tried it on friends account, long ago, right after beta and from what I remember it was mostly a vast world, vastly empty with a lot of fetch quests, go talk to... and push a button quests.
Definitely would be more inclined to go through the grind if the gfx were on par with the CGI in the cinematic, but if it's F2P, it doesn't hurt to give it a go.
Old Republic canon is boring? lets agree to disagree here, lol, it's SW for grown ups
Lightsaber duels, death and destruction!
I for one love the old canon, powerful Sith & Jedi, ruthless Eternal Empire, in fact, I can't wait to see what David Benioff and D.B. Weiss will do with that portion of SW universe, if it's anything like Game of Thrones, it's going to be epic.
+1 for Kotor 3
