But you're not grounded in reality. You just argued that making a ton of good games was bad for the Wii. Having a diverse library with many great games is what lets a system survive so well in droughts. If Nintendo didn't release all those huge games so fast, their current drought would be 10 times worse.
And core games sell better on the Wii than on the 360 or the PS3. The Wii is winning the old war and the new war. The 360 and the PS3 are fighting really hard in the old war, and barely losing. But in the new war, they've got nothing on Wii Sports. As long as they're only seriously competing with Nintendo on one of their 2 fronts, they will eat Nintendo's Wii Dust.
