Well, my earlier posting wherein I suggested Platinum, insistent on securing more independence and becoming their own publisher, wasn't going to looking to be purchased at the present time sure aged well. I was expecting it to happen eventually, but not near this quickly.
They wouldn't be in this situation if they'd just gone ahead and made that
F-Zero Hyper Stylish Racing Action Game.
On a more serious note, as this is about Nintendo's stance on acquisitions, if Platinum were to find an acquisition by them favorable, this does seem like a situation where Nintendo might be interested. They've maintained a partnership with Platinum for some time now, and interviews from the Wii U era indicate the studio works well with them, that they're supportive, allow creative freedom, and so forth; by these accounts, Platinum and Nintendo actually mesh pretty well, with Nintendo bringing out the best in Platinum.
Where acquisitions are concerned, Nintendo is primarily interested in the talent, which is exactly what is acquired with Platinum; if Platinum weren't interested, if an acquisition might lead to talent leaving and the studio becoming an empty shell, then such a purchase would be pointless.
What exactly Platinum is looking for, as far as freedom and independence, would play a big part in whether Nintendo might possibly be interested. Creative freedom, Nintendo might be willing, though as a guiding hand -- the creative freedom wouldn't be absolute, though perhaps more than might be afforded elsewhere. Putting games on any platform at will, unlikely.
There are, of course, buyer possibilities that would likely mitigate noticeable impact on operations -- at least for the time being. Though something like Tencent, perhaps one of the more likely possibilities, wouldn't quite sit right with me.
The obvious solution is for Nintendo to do some good old-fashioned talent-poaching.
The first step is to loudly talk about how people who work for Microsoft or Tencent don't get to make any Bayonetta or Astral Chain games. Then you pay people who are very clearly not Nintendo employees to talk about the cool swimming pool full of cash, how friendly the Monolith Soft Kyoto studio are to EPD people, and about how having tea poured over you by Miyamoto is actually kinda refreshing. Then you have Furukawa and Shinya Takahashi taking it in turns coincidentally walking passed Platinum's HQ loudly lamenting about how much of a shame it is that they don't have enough staff for Astral Chain 2.
And then?
The rest of the dominoes will fall like a house of cards. Checkmate.
Of course, you missed the obvious step of literally dangling
Star Fox and
č¬ć®ęéØå, Nazo no Murasame JÅ in front of Kamiya. Nobody can refuse the call to save those.
