I really love 5 despite its flaws. It is my favorite NES Mega Man game. The buster is OP and makes the game a fair bit easier, as a lot of enemies will die to one charge shot. The robot master weapons are pretty bad overall but I still find enjoyment in trying to use them anyway. Whenever I need a Mega Man fix I can boot up this game and run through some stages and enjoy the music. It's the coziest mega man game.
