Nintendo just knows how to work with what they have. thats why so many people want them to take the jump and make a new powerhouse console like they did in the 80's. they would have the best IP's, the best graphics, and 3rd parties would praise them

When their biggest franchises are concerned (Mario/Mario Kart/Smash) Nintendo has always been able to push the limits of their hardware farther than seems possible given the other games.

Mario Kart 8 was indeed gorgeous, still don't know how they did it.

It is aesthetically pleasing. But I wouldn't call Mario Kart 8 a graphical powerhouse.

It's underpowered, because when it was released it was underpowered against the consoles that it would eventually compete against in its generation (PS4/XB1). However, whoever says it's weaker than X360 or PS3 is trolling. Specs are better by a decent margin.

Had it been released when the PS3 was, it'd be a beast (aside from the fact the the online play was still way behind).

Have you play Smash Wii U 8 players (4 clouds) or eve 8 clouds? it gets really laggy like 30fps or less.

It is underpowered but still capable of producing some decent looking games.

"It's mainly what killed it."

"lack of power wasn't the only problem." 

Mainly (definition) : for the most part 

mainly =/= entirely
