Maybe achiving a level. But i would like to seperate "making some number go up" from the fun of solving a challange. The joy is not only in having solved a challange, but also in trying to jump that one gap 100 times until you nail it. Same goes for plain action, there are a few endless level games where the score is insignificant, it just gets harder and you try to stay alive and the fun is reacting fast.
