I don't think it'll put that many kids off. Parents who look at this game will see a fantasy game in which you use magic to defeat bosses. Kids are going to think themselves "cooler" for playing an adult game and may be more likely to want it in the first place. Parents are not going to see it as much different to any other MMO... and considering the number of digital purchases, many teens won't even need to get their parents to go into a store.
