I don't think the nudity should really be a concern.
People who download and log onto the game know exactly what they're getting into and there's a very good chance that the nudity is the reason they're checking out the game to begin with. Let's not kid ourselves. Censoring the game would be removing a reasonably large source of the game's appeal.
Just throw a mature content disclaimer on it and let parents parent their own kids. If parents don't want their teenagers to play games with boobs, that's their business, not ours and not Aeria's.
Though anyone who thinks that they can prevent their teenage kids from seeing boobs on the internet is a rather misguided soul.
I agree with this statement 100%. Although if I'm not mistaken, the sentinel class is an actual little girl, so I don't think AGE would have an excuse to not change it. (Unlike with the Elin race in TERA, whose members are in reality almost all over 1000 years old, just created in the image of their goddess's youngest daughter)
Also, this game is built around having females as the only playable characters. Respect what the developers wanted to do with this title, or just suck it up and stop whining.
