Mario can't even spell "doom", to busy selling insane amounts of games and systems.
I think the Wii took everyone by surprise and pushed Nintendo from last place "might be out of the business" to first place "Top Dog" so there's a backlash from that.
At the end of the day it's just video games though, I like having Mario, Link, Master Chief, AND Nathan Drake here.
From zero's back to being hero's, Mario, Link, Samus, Donkey Kong live on!
