jtogel writes "Many games use 'rubberbanding' to adapt to your skill level, making the game harder if you're a better player and easier if you're not. Just think of Mario Kart and the obvious ways it punishes you for driving too well by giving the people who are hopelessly behind you super-weapons to smack you with. It's also very common to just increase the skill of the NPCs as you get better — see Oblivion. In my research group, we are working on slightly more sophisticated ways to adapt the game to you, including generating new level elements (PDF) based on your playing style (PDF). Now, the question becomes: is this a good thing at all? Some people would claim that adapting the game to you just rewards mediocrity (i.e. you don't get rewarded for playing well). Others would say that it restricts the freedom of expression for the game designer. But still, game players have very different skill levels and skill sets when they come to a game, and we would like to cater to them all. And if you don't see playing skill as one-dimensional, maybe it's possible to do meaningful adaptation. What sort of game adaptation would you like to see?"
