Alright, I was screwing around with exp and i thought what notch might do with it, and i started thinking of skill trees. You know, branching out in different ways to be unique. And then i thought, now what we're gonna have NPCs (and apparently we're going to be able to be the arbitor of their problems?) why can't we have the choice of being an ass or being a saint having a reward?
Maybe different levels of this karma system will do different things for a player?
example: completely evil would make animals scatter from you on sight, NPCs attack you without reason, Endermen will be passive or even friendly to you?
It adds a whole new plane to the playing field. Im not trying to make this a suggestion for notch to add (if i did, i'd add it in the suggestion section) but idk, i just wanted to see what the community would think if minecraft went down this road.
I've never liked karma in video games, and mentioning Fallout, Fallout 3 is a big reason. How exactly do other people know I've been stealing? In New Vegas they switched the focus to reputation, which made much more sense, and they should have completely gotten rid of karma.
If there must be karma in a video game, the only thing I think it should ever effect is your character's luck, and not even that strongly. Sometimes good things happen to the bad guy and bad things happen to the good guy.
That or it's a game with clear gods affecting the outcome, and 'karma' is really just how much they like you. Minecraft has no such thing.
