I am looking forward to the game, it looks beautiful and I like the idea of a new take in "gaming" (i.e. I have no idea what the gameplay is like).
Anyway, I find ti strange to say it'll be a game for "adults". THe stereotype of the bad-mouthed-12-year-old is just that. A stereotype. The main problem is that human averall are fickle creatures that have different tastes. So just because someone is grown up or an adult, does not mean that he won't feel like trolling a bit (see SA forum goons), or simply thinks the game should be played a different way than you.
In the end there is no way of making a game that avoids player driven conlict more than you can create world peace. The best you can hope for is a community of like-minded people that can play together. But if you get there you probably havea very narrow audience (Also see "The endless forest")
