I didn't like SA much, the theme/characters just annoyed me. I don't like the whole "ghetto, dawg, bitch what bitch" kind of stuff, it's annoying and really turned me away from the game. I much prefer the mob theme/characters.
Can't say much else on the world/missions, as I literally stopped playing an hour into it cause of the characters/theme.
Exactly the opposite, i'm still young and listen to rap/hip-hop the most so no surprise there. Having fun with SWTOR a little and thinking what should i play next. Perhaps the Batman series.
