What are you talking about? That's great! They're not relying on heavy and pretty graphics. Nintendo has always been about creating better gameplay and experiences than graphics. Ever since they first started in the gaming business. Sega always had the more powerful consoles. The only time Nintendo had better hardware than someone was with the GameCube to the PS2. I'm more than ecstatic that they're not falling to all the crybabies this generation and trying to pump out the most awesome hardware.
You're completely wrong!
SNES was more powerful than Genesis, and it' proved with DKC.
N64 was much stronger than Playstation and Saturn!
Gamecube as you said was stronger than PS2!
