One funny thing about the accusation that Nintendo is killing hardcore gaming.
I didn't purchase a console in the last generation, and my PSOne was bought used from my roommate.
I only purchased a Wii because I played WiiSports at a friends and loved how unique the controller structure is.
Of course, my favorite games that I have invested the most time on the Wii are what you might call hardcore games: MP3, Zelda, SMG.
I have plenty of casual games (Warioware, Boom Blox, etc.) and those are great when you have 15 minutes or have friends over, but if not for Nintendo creating a unique gaming system that was also affordable to draw me in, I probably would have sat out this generation.
