Let’s address these one at a time…
The hardware is weak, but the market has spoken and to them at least, it doesn’t matter. If it DID matter, people wouldn’t buy them. Why would Nintendo spend the extra money when consumers have already decided they’re going to buy it in droves anyway? So they can spend more on manufacturing and make less profit? Yes, they wanted easy cash. What responsible company doesn’t? It doesn’t make any sense to spend a dime more on producing a product than what your customers demand. The limitations of the Switch are the fault of consumers who buy it, not Nintendo’s. If Microsoft could sell the same number of units Nintendo can by making a game system that cost $50 to manufacture and ran on 386, you can be damn sure they would too. I completely understand your anger - I’ve had to spend the last 20 years watching flocks of people buy inferior, overpriced Apple products and rave about how great they are. But like Nintendo, Apple only does it because the consumers let them get away with it. Your complaint is misdirected when it should be targeted at the customer base. But good luck teaching happy people who don’t know any better that the thing they like is bad. It’s not a great use of your time.
All of your other problems are perfectly reasonable, but if you think Microsoft’s plan if they buy Nintendo is to drop everything and start porting old titles or working on a new Starfox game, I’m afraid you’re going to be disappointed. Like Disney buying Star Wars, get ready for annual, mediocre entries in your favorite series cranked out by a revolving door of existing teams to maximize output. After a couple years of half-baked Mario and Zelda games, they’ll stop selling in the numbers Microsoft wants, and after the golden goose is dead, they’ll dissolve any remaining Nintendo assets into their larger acquisitions structure, lay off a bunch, and put the name in the vault while they look for something else to cannibalize.
Are you me?
