Really doesn't matter about this investing part. All the OEMs invest in the games they set for their own system. They all play the exclusive game. They all play the moneyhat game, they all purchase and acquire studios big or small. This is the game being played and its not for the weak or you find yourself a Sega, Atari, Intellivision the list goes on. Basically all you saying is play like I want you to play but if every company played that way, they would be out of business. Sony doesn't care that Xbox only gamers will never see Spiderman or any of their only property, their stance would be get a PS5. MS and Nintendo have the same stance. You want to play our games, you get our system.
The thing is nothing is unfair. When opportunity comes, you either take it or sit their thinking what could have been. If Bethedsa and ABK is up for sale exactly what you expect MS to do. Say oh, Sony does not have enough money to make a bid, we should just step away. No business is going to step away from an investment that lands at their door when they have the money to make a move. That in itself would be dumb. There usually no second chances which going by your on telling on the Spiderman IP. It was stated MS had a chance first to do the game but refused. They had a chance to get Genshin Impact on Xbox and refused. As we have seen, refusing opportunity can cost.
Money hating is okay, doesn't bother be. The developers and publishers still an independent company and can choose whatever they want. They will be the ones making the profits too, so they kinda balance the power in the market
Buying out other companies however is predatory. I wish regulators were more rigorous when blocking this kind of acquisitions. Microsoft has enough studios already, Zenimax acquisition already granted them many big titles. They shouldn't be able to buy another big publisher.
Its not a question of what bothers you, I am saying what bothers a business. For MS, as a business and in 3rd place, the investment to out money hat Sony is steep. The market leader gains an advantage because as long as they can make these deals at a much cheaper rate, it takes twice the capitol for MS to to even compete. So for MS, what is best for them, trying to match Sony and paying 100 million dollars for a year of exclusive which mind you was the going rate a while ago compared to taking that company out of the picture.
What does it mean if its a publisher or a bunch of studios, its pretty much the same thing. If Sony purchase 5 studios would that equal to most publishers output. Either way, as far as I am concerned, I am only looking at the landscape. 3rd party lockout deals always favor the platform with the biggest install base than the smaller one because you can easily wait until that game releases but if you are the market leader it helps more to protect your market share as consumers would be less inclined to leave when they get things first.
For each OEM, any of these companies purchase a studio its off the board for another platform and none of it has anything to do with how gamers feel. None of them care, they care about their business and you as the consumer only benefit as long as competition remains strong among them all.
