Miyamoto - Wii Music is hardcore? Hardcore = amount of time spent playing?

[c0rd]

@Dodece: What are you talking about?

Okay, fine. What games do you consider "hardcore?" I'd love to hear it. The fact is, people that play things "hardcore" in itself is an obscure rarity. Is there some sort of minimum # of players playing the game so intensely for it to qualify as "hardcore?"
