Seriously, what is with that? Why does everyone seem to almost hope that Nintendo goes broke, despite them being one of the companies least likely to?
Lack of stable online play.
Lack of online play and or features in most games.
Overbearing censorship in games.
Lack of graphical potential when compared to other competitor consoles.
Lack of listening to fans in accordance of which games should be ported / remastered or flat-out have a new game in the series made (I.E. where is Metroid's new game for 3DS still?) or even simplistic things such as features that should be added to remakes or new installments of games.
Total opposition within self. By that I mean Miyamoto is notorious for saying he will do things or not do things and then doing the exact opposite (such as his declaration of 'we will stray from family-friendly and go more mainstream / adult' that he has been campaigning since the N64's release.
Lack of control options in 1st-party titles. Seriously, I've noticed many 1st-party titles do not have control options. Especially games that need one, such as SSB for the 3DS. I'd have bought the game if I could use the D-pad... you know.. like fighting games were MEANT to use since NES days.
Gimmicky 'features'. Rather than take into account the fact that most gamers still claim the SNES was the best console made to date by ANY company, Nintendo keeps shying away from what gamers truly want by trying to 'reform' the concept of gaming. Miyamoto has even worded it as such when he said 'I am always trying to redevelop and re-imagine gaming from the ground up to make it 100% new'. That being said, rather than focusing on "here is a controller with buttons. have fun!", what we, instead, get is, as I said to Porkman, a Bop It game with a screen attached. Nintendo focuses too much on "twist this. poke that. shake the other thing" and other such impracticalities that are totally unnecessary in a gaming world. It is fine to have these features, don't get me wrong, but focus full games on them and not just toss in pointless gyroscopic controls or whatnot (such as the beam-walking in Luigi's Mansion: Dark Moon) and for the love of all gaming, PLEASE stop indulging so much R&D time and money on that BS!
Horribad marketing and advertisement / PR management. I doubt I need to pin examples to this, but seriously, it seems as if every time Nintendo does something PR-wise it is a step backward. Even when it isn't advertising, they just do foolish moves and never go back to fix them (like removing spotpass from Swap Note / Letter Box). I mean, heck, even Microsoft fixed their major blunder with the Xbox One's gimmicky release. Feel free to drop the STACK of lawsuits against Nintendo that all were won in favor of the other parties that sued them - all for theft of designs and concepts - onto that pile of awfulness.
What sucks is, because of all of the above, third-party developers want little-to-nothing to do with Nintendo's consoles, which severely limits the library in console-exclusive games. Given the choice most people would opt for even a PS3 or 360 version of a game before a Wii U. This also makes the Wii U a huge waste of money for its price, still, to most people. Couple that with the craptacular internet that Nintendo has for a server and people such as myself who rely on online play and have absolutely no local gaming capabilities are going to veer toward Microsoft's consoles because with Gold status you also get game-specific servers which increases stability and lessens lag as well as disconnects to VERY rarely (unless your personal internet is horrendous. Mine is bad as heck and I have no problems). Even Sony suffers from the same agonizing single-server problem Nintendo does, but their server is much more massive (actually, I believe when I last checked they had 3 servers, but each is still larger than the sum of whatever Nintendo has).
I used to be a die-hard Nintendo fan - as much as I was a Capcom fan, actually - but much like Capcom, Nintendo's lack of reasoning, compulsive lying, and refusal to remember 'the fans come first' is what makes me stray from them almost completely, nowadays. I'm not hoping Nintendo goes broke or closes down, but I certainly DO feel it is time for Miyamoto to retire like he said he was going to before he released the N64. With all due respect to a now semi-senile man who was once a great creative designer... it is time for someone else to accept the throne and save Nintendo from themselves, in my opinion.
