the ingame aspect: Well to be honest, the concept sounds very cool. I would love some insanity and chaos in this kind of game. But indeed the fact remains that in this way players might feel limited in how they should play, they will at some point be "forced" to meet up with other players to keep their sanity in check. As a "friendly" player myself, I totally would support this, because players will have to team up more often. But as a gamer I wouldn't wanna see other players (even bandits) "forced" to play a certain style. Because after all that's what makes this game so awesome, there are no set rules. Players get to chose and nothing -how awesome a certain feature might be- can come between a player and his/her ingame freedom. On to the realisme: If we would compare this feature to real life, I wouldn't be to sure about it either because no social interaction doesn't necessarily mean insanity. Issolation (as IE a issolation cell) will trigger synthomes of insanity and eventually insanity. But no social interaction in the context of living alone in the woods for a long long time doesn't make you insane. It makes you less capable of dealing with certain social situations. It makes you a bit "strange" and "awkward" from an other person's perspective that does participates in social interaction. Infact you become a person that other people don't want to be around because of the fact that you will not be used to human contact anymore as a direct consequence of being alone for a long time. My conclusion: I like the concept but I would rather opt for a (slight) decrease in humanity when you haven't interacted with other survivors for a while, In this way other players might see you as a threat due to the fact that you have a lower humanity. But this option would only work if we would have the possibility to create a party/group ingame, because there isn't a set definition for what is or isn't social interaction ingame. Sorry for my english i'm used to speaking dutch. AND this is just my opinion so, nothing bad intended^^
