Nintendo needs to take a lesson from Disney (and some ideas).

[Nem]

Its a bit silly to compare Nintendo to Disney... but alright.

Assuming Nintendo is willing to spend their money in the bank to go on a purchasing spree, wich they clearly arent lets think about what they can do:

Buying Microsoft is not possible.
Buying Sony is not possible (too much baggage and debt).

So, the only way is to go around buying third parties. This in itself is not as easy as Disney.
Lets start with the US.
Should they buy EA? Can they? EA's only worth is the FIFA franchise. Their are doing an incredible job ruining everything else they do as usual. Bioware? There might be some worth there, but EA is running it down, like they did every other developer they bought. It wont last long.

Bethesda? Maybe, but wouldnt this only generate hate in the west for Nintendo and blocking bethesda games?
The same could be said about 2K, or Take 2.

Ubi soft? Makes a bit more sense.

Activision? They only have 2 franchises. They are a time bomb waiting to explode. Once CoD goes, Activision is finished.

So, the only market where they wouldnt be hated for aquiring other companies would be Japan.

Buy SEGA? Definitly yes. Didnt need any Disney example to say this.
Square enix? Would've been a good idea before last gen. Now? Nope.
Capcom? Not a bad choice, just like SEGA. But they are not doing so well financial wise after so many duds.
Konami? Konami is already dead. With the fading of Metal gear solid, they will be done.
Namco? Not a terrible idea.
Tecmo? Not that big.

End of the day, this will not affect Nintendo in the west in the least.

The problem with aquisitions is how they are perceived. Disney buying Lucas film... i am still to be convinced it was a good thing. Marvel, definitly is working in terms of movies though.

Final line. There is no comparison with Disney. Its a very different market. Nintendo operates on their own platforms, Disney doesnt. Disney movies are widely available on any cinema or DVD shop.
What you are trying to say here is: Nintendo goes third party and buys other developers to make themselves bigger and more relevant.

Now tell me, how has that worked out with EA? A giant that eats talent and spews out crap.

At the end of the day this is an incredibly risky strategy. I do think Nintendo should buy SEGA and have them develop more and better games.
RARE? No one cares. RARE as we knew it in the past no longer exists. Actually if Nintendo were to buy SEGA, they would have to rehire the likes of Yuji Naka and Yu suzuki once again.
