So, I really like platformers, but after you finish the games the replay value diminishes until you "rediscover' the game a while later. An example would be Mega Man 2, while a fun game, after you beat it it's not like you're going to pick it back up the next month. I really seem to like the games in which achieving point scores is the end goal (i.e. Tetris, Donkey Kong, Pac Man, etc.). These games have continuous replay value as you are always competing against yourself, trying to beat a personal best score. I have Tetris, Donkey Kong Classics, and Burger Time and was considering getting Popeye. Let me know if you can suggest any other games for the NES along these lines.
