And yet it's incredibly successful. So what do you want, Ian? I reward innovation/integrity/other uppity ideals as much as any other games elitist, so I don't buy these games. But it's making Nintendo money. Why would I expect them to stop? They're still releasing new games that I enjoy.
Anyway, it's not as if these versions are simply emulated ROMs and nothing more. They have save, wireless multiplayer, other additions. There is appeal, even in the face of cheaper versions. It's there, in a cart, with added features. Only $20.
