I'd play Mother pachislots.

But all they'd want to make is more Mario ones.

Even when the Wii U had third party support it was failing, so I don't see how its current poor (but slowly improving) sales are an indication of the importance of third parties now.

I doubt anyone stuck with Capcom or Sega would object to Nintendo taking the reins, and Capcom/Sega aren't exactly the powerhouses they were a few generations ago, so I doubt Sony, who's not exactly the most stable financially atm, is going to get into a serious bidding war with Nintendo over them. I'm also well aware that it's not like purchasing bread at the market, I thought it was obvious that easy was meant in relative terms.

Also, have you seen Resident Evil 6? Nobody could ruin that series harder than Capcom has done. There's only so low a series can get before it plows into the ground. And you think Nintendo would ruin it? How many games in recent years has Nintendo produced that were even 1/10 as bad as that steaming pile Capcom laid in a game case and called RE6? I can't even recall one.

Watch Dogs, boosted the PS4 sales a lot. Even in Japan with Wolfenstein and a FIFA bundle the PS4 got a nice noticable boost. Everyone Microsoft, Sony and Nintendo needs 3rd party support. The problem is Nintendo always know to make make a console with a weaker hardware or with a different CD size.

That is what i said! Did you read my comment? Or merely wanted to make a cheap jab at nintendo?

Company i work for has just been sold for over 1.5 billion, yet you'd be surprised how moronic and out of touch the guys at the top often are.  And the last thing any one of them is willing to do is throw money at a problem.  They are awful at revering anything.  They  are barely ok at making things go well when things are going well. 

Usually these days you grow and things are good, when things are bad you out grow them and if you cant you are fucked.  Ninty is one of the best corps in the whole  world at making a go out of very little and thriving at small market shares.  But even they are clealry held back by the guys at the top, and no better proof of it then how the wiiU has been handled. 

Please elaborate.

Yikes, not another one of these types of threads... Not even going to read it but the only reason they wouldn't need them now is because they are content with the low sales they will have with the Wii U and are now looking forward for their next system

They should buy Square Enix when mobile games will ruin them

I don't think buying Capcom is necessary in any sense. Sega, I would love for Nintendo to buy - between Sega, Atlus, and Nintendo, there's a broad array of franchises to choose from, and the three distinct brands would be useful for better targetting of products and avoiding image issues.

That all being said, I could easily see Nintendo approaching certain publishers with a deal - they'll bankroll a heap of games from those publishers, on two conditions: the games have to be for Nintendo consoles, and they have to be subjected to Nintendo QA (not just the bug-testing kind that is needed to publish on the system, but full QA as used internally).

The benefits to the publisher are threefold: they minimise financial risk, since Nintendo is bankrolling the development, advertising, etc. They minimise the development risk, since there would be no inherent restrictions on franchises, etc (although Nintendo would presumably be able to veto obvious selections of franchises that don't even have a chance of getting noticed - this means that developers are much more free to develop the game they want, rather than having to explain why it'll be a big-seller. And they get the benefit of Nintendo guidance on their franchises, which they may not want to admit to, but it would be incredibly beneficial to them.

Sega, Capcom, Tecmo Koei, and Namco Bandai would all be great candidates for this sort of deal.

Real world does not work like that.

Buying them would be massivly costly, intergrading them into ninty would be cotly and be a massive pain in the ass and likely massive loses would happen as it happens.  Puting the ninty touch sounds good but it would take years to reap any benefits while in the mean time costs would be massive as would losses.

Aka your fantasy just sunk Ninty.

ps Ninty makes plenty platformers not maned Mario, and all sale NO where near Mario.
