But why tho?

Bigger sales failure than the N64, Nintendo repeated many of the same mistakes. The N64 was the most powerful console in it's gen, its only flaw/mistake was going Cartridge. It has some the greatest games ever made in its library.  For my money out of that list the Wii U is the big failure. 

I wanted to say Saturn, it was hard to develop for that system, sold terribly, but alot of it was Sega and not the system itself.
