That's not true. It's trivial to create a game that will take arbitrarily long to win by just increasing the number of times the user has to perform the same task in order to advance. That is a trade off against being boring, but having developers optimize games to explicitly be as time consuming as possible and just not-boring enough that you don't quit them in disgust is not really a helpful incentive.
