what does any of that have to do with NSMB not being awesome. so it doesn't have incredible photoreal graphics... umm it's MARIO!... and it's got awesome gameplay. it's a great gameplay, arguably the only great game you can only find on the WiiU atm.
The gameplay had been done to death and improved graphics are one of the main reasons people buy new consoles. The trouble is that NSMBU has bad graphics and doesn't compete with contemporary titles, like Rayman Legends. It really is a classic case of a rehash that achieves nothing.
I fully expect the nextbox to have a new Halo, and I fully expect the game to play almost exactly like Halo 4, which basically plays like Halo 3 and so on, just minor tweaks along the way, just like Mario.
And people rightly criticise those games as well, so I'm the last one to defend that sort of behaviour. However, at least each new Halo game pushes the envelope on graphics and art direction - they're offering some new for fans. The original Halo was groundbreaking but each successive game has been less relevant; it's the same with the Call Of Duty series since Modern Warfare. The real sequels are games like Far Cry 3, Crysis 3, The Witcher 2 and Batman: Arkham City - where they substantially improve upon the graphics, gameplay and direction of the previous games.
Personally I think the art direction of NSMBU is worse than that of NSMB for the Wii. It's very sterile, the animations are stiff, the colours very stark - it just doesn't sit well with me. Nintendo used to innovate, used to lead the market - now they're putting out one derivative title after another. Their games sell because of nostalgia, not
