the WiiU's problems stem from,
the name,
price,
number of games for the system,
type of games for the system,
lack of choice of games (no third party support) ,
no MUST buy games,
lack of marketing,
lack of investment in R&D,
lack of direction,
poor digital market system where games are tied to the console,
the main selling point (gamepad) is not used & seems to be a gimmick,
poor online gaming set-up,
another issue is & i know i will get slated for this, but the system power, GPU, CPU, RAM, HD is not on par with the PS4 & X1, especially for people who do not know their stuff, whenever next-gen games are mentioned the WiiU is not mentioned alongside the PS4 & X1, now obviously everything is dandy in hindsight but Nintendo must of known that Sony & MS were going to go down the power route this coming generation because it is what everyone has been crying out for, yes ok power is nothing if you don't know how to use it, but not being x86 is just one issue in the hardware stakes, of course Nintendo didn't know that the PS4 would have 8GB GDDR3 RAM & that Kinect could detect your heartbeat but the lets go small & low power has left Nintendo on their own, but is it the was forward, no, the size of a console doesn't really matter as long as it is not huge then any size is ok & as long as it doesn't need a mega-watt of power per hour to run it makes no difference how much power it uses, ok if you have to put a dollar, pound,yen, euro in the meter every hour to play on your console, but how many have to do that, yes it is good that there is the tech to do this, but that is just like saying there is more tech & power in my iphone than took man to the moon, well lets see you go to the moon using your iphone then !
there are just too many problems with the WiiU & no one person or company can sort them out, Nintendo should of learned their lesson with the 3DS release because the WiiU has the same problems the 3DS had in its early days, but don't forget that games have been moved to the 3DS or ported to the 3DS from the WiiU, so is there really any point in a WiiU when you can just get a 3DS/2DS ?
i had a WiiU since release day & do i regret buying one, yes i suppose i do because i feel let down by Nintendo mostly, they promised so much with the WiiU & have not delivered.
