In the presentation Vengeance did for the google thing, one of the things that sticks in my memory was the concept of "diminishing returns" as a way to stop cheaters. Basically, it means that the more you do something, the less incentive you have to do it. An example would be mining. The longer you mine, the less of a chance there is that you'll find anything. Eventually, you won't be able to mine successfully anymore, and you'll have to take a break. Vengeance thinks this will help stop cheaters, and I think he's right. But can we also use this on powerlevelling? When mental stamina was introduced to the game, part of the rational for it was to force people to take breaks from mining and killing things so that they would spend more time actually talking to other players and connecting socially with people. The problem of course is that if you level your character enough, it's very difficult for you to run out of mental stamina. Anything we do with stats and fatigue will end up affecting new players the most and levelled characters the least. So how about "diminishing returns"? Is there a solution in that?
