Meh, I’d argue it offered one of the most compelling things for the Star Wars universe and lore. I don’t see how SWTOR did, especially since Revan is a complete joke in that game.
I don’t really care about Revan side story in SWTOR (and I agree that the side story related to him is super crap). All I care are individual storylines of main characters and the main Sith vs. Republic setting. That stuff is for me one of the best Star Wars experienced for far.
Especially I like the the two Sith and the Imperial Agent storylines. It is basically the first time I could properly experience being an Imperial/Sith in a game. I also like that things are not presented in the usual boring “imperials bad, republic good” black-white contrast. Things are much more practical, down-to-earth and grey.
