Are people still thinking the weak hardware is the reason the Wii U is flopping?
I can't believe people forgot the history taught us not only once, not only twice but multiple times that hardware power does NOT generate sales. If so, the PS2 would have been way behind the GCN/Xbox because it was significantly weaker.
It's all marketing. Marketing made the PS1 sell. Marketing made the PS2 a behemoth. Marketing made the DS a beast. Marketing made the Wii a must have. Similarly, lack of proper marketing made the Wii U flop. It's so simple.
And seriously, I don't get gamer's obsession with power. Nintendo's developers at least use the console to its advantage not only to get the best possible result, but also to get 60fps, which is the most important thing technically. Xbone is struggling to get that, and there's been an abundance of games with technical hiccups last gen on PS3/360. (Hilariously enough, the Wii was the most consistent in terms of frame rate.)
All said and done, game design is really what matters the most. The one difference that 3D World on PS4 would make, for arguments sake, is better graphics. But the game on the Wii U is already a looker because of the proper use of lighting and art style (and it looks better than Knack because of that. Art style > power), so it's not like it's THAT much of a loss.
And if power is really what matters, everyone and their mother would invest on a PC. Why bother with a PS4?
Really, that stupid ass name and Nintendo's incompetence is the Wii U's biggest downfall. Not the hardware. Not the games.
