I have 2 games physically, which frankly is one physical game too many (would prefer to never have to swap out any cartridges), and my other 14 games are digital, which I really do prefer. I know the arguments against digital, and to an extent I understand and even partially agree with some of them, but there really is nothing like being able to quickly go from playing one game to the next without having to physically do anything beyond hitting the home button and selecting another game.
