This game doesn't need this. What it needs instead is bug fixing, animations improving, and so on. In addition to that, a feature that would make this thread pointless is the ability to make groups and for once use the Group Communication properly. You stick to your group not to the world classification. If you are afraid that sooner or later someone will betray you, end your long time character who you spent so much trying to build, just follow your instincts and keep that person away from you. If they implemented something like this, it would just be a game braking mechanic. Would make the game like any other game out there that is dull and stale. This game is great because is free from all those stupid mechanics. That is what makes this feel unique among all the others. What makes this game awesome is the fact that you can't tell who is friendly and who is not. The thrilled that drives you to be afraid or careful about meeting others. Take in consideration the immersion that this game already produces on you. Stereotypes should be kept away from the game. If they implement clothes and skins, then clothes and skins should be optional. Have you ever thought why this mod (soon to be game) is so popular? Is it because it is just like any other game with helpful HUD and everything else that can help you identify good or bad? Or is it because it has its own authenticity? Not being able to tell what is good or what is right. In the end, this is just a game and things like that can still be implemented. But this game is great because it is able to standout as different. I do understand that many people would love your awesome system. But think about the great majority of people who plays the game because of the originality factor. I'd bet you anything in the world that people have chosen this game for one reason only. They are on their own. They choose what to do on their own, they do not need help from a system like this. Certainly the system that you present is very interesting, but not for this game. Tl;dr: Immersion braking mechanic.
