Tetris and any RPG I like to start with. Something about hitting level 30 when I should be level 10 that makes it fun. Not mention trying to max out and collect everything in the game over and over. This is why Pokemon can become a nightmare. If my other Pokemon are level 40 I must make the new one I just got level 40 too! Must all be same level even if I never really use them to progress. Same with a lot of platformers.
