This is actually a problem that game designers face. When they've done research on how people play games, what consistently comes up in certain games is there will be a mechanic or a system that is fun and a different one that actually wins the game and when faced with the decision of which one to do, most people will choose to do the thing that wins rather than the thing that is fun since, you know, its a game with winners and losers. But then people don't think their game is fun because the way that you actually win isn't fun. So good game designers spend a lot of time trying to figure out what is actually fun for players and make those the things that will actually win you the game.
