They had all the time to do it since the OG XBOX and still have money to start off gradually. Games arent supposed to be released on one batch regardless. There are other talented studios out there too they could invest in instead of buying off Zenimax and ABK. These studios produce as we speak. They also already acquired exclusive deals with 3rd parties. Everything else about needing specifically those big studios that own these multiplatform franchises is just an excuse. It is obvious that this move was about owning significant existing multiplatform content away from competition
If MS is unable to do what Sony did with so many resources then their incompetence should be reflected in the market. Not "punish" competition and remove accessibility from consumers from many games unless they buy their platform because MS just sucks at it
Also there is a lot of contradiction by supporters of this move.
One one hand they are like:
"MS did well to make these multiplatform games exclusives. They need it because Sony is stealing exclusives (which they really aren't)"
And on the other they are like: "MS is good unlike Sony, and they wont really make these games exclusives".
They should decide what their argument is.
But we're beyond that now right, those days are over, and few studios are made from scratch because of how complex studios are. If creating a studio from the ground up is such a viable strategy, then Sony wouldn't be closing some and acquiring others, it's just not a reasonable strategy anymore for players in this space. While it's true that MS had since the beginning to make these studios, MS is not nearly committed to gaming back then as they are now, both Gates and Balmer did not take gaming as seriously as Satya. You're seeing a very different Microsoft with a very different strategy and other players in the market are making moves as well, like any company they still want to get ahead. It's no different than Sony buying GaiKai, they've had forever, why didn't they make that from scratch but MS was able to?
We can point all sorts of fingers about the past, the reality is, each company has an easier time at doing things than others, and we're at a point in time in development where honestly AAA development is much too expensive, too labourous, too specialized, and quite frankly risky on return to grow things from scratch. The expectations for these games are way too high, perfect story, perfect game play, best visuals, best multiplayer, best open world, best online play, best connections etc. It's too much and too hard to do things from scratch. Acquiring the talent you need is the way that the big 3 will move if they need that talent.
To be fair, MS is also creating studios from scratch and building up a number of smaller studios into larger ones. Acquisitions for them is just more of what they want, and where they want to go.
It doesn't bother me that they grab COD because anyone paying attention to how all previous king of FPS games have died out, COD turn in the sun will not last forever. To that end, I'm not even sure it matters that COD goes exclusive for next gen, people may not care, like they no longer care for Battlefield, Halo, Gears, Quake, and Doom. Right now it's fortnite, apex legends, counterstrike, valorant, COD and Destiny. Something will cycle in and another will cycle out, OW2 is currently growing in size now that it's gone F2P and this will likely cause something else to cycle out. That's why I don't think this deal is as lucrative as people are making it out to be, ABK is shrinking as a publisher because they continue to pour all their resources into COD, and COD continues to shrink out of relevance. The FPS market is only so large and competition is heavy in that space.
As for why MP content is important, well, it's because MS sees MP content as the metaverse, and they want to build their version of the metaverse before the other silicon valley players get a hold of it. Which sounds as stupid as I write it, yet, it also seems to align with their strategy of appealing to this digital life/twin in the form of gaming. They own Minecraft, they may very well be interested in buying Roblox for the same reasons.
I can't tell you that it's a great for the industry, all I can say is that, acquisitions are the only thing that makes sense now, and if you're going to risk making a new studio for any purpose, those investments will be small until the formula is clear to proceed with additional investment.
Personally, of course I welcome MS taking over ABK. I don't care for COD personally, but if you're going to pay the largest price tag in merger history, you should want to get it all.
But at the same time, since MS has started making serious investments into games again, particularly the PC space, we're seeing a resurgence of types of games RTS, Flight Sims that largely died out when ABK decided the Blizzard IPs weren't worth supporting anymore because it didn't make as much as COD. I welcome a new MMO to replace WoW. I welcome new RTS games, as we've been waiting longer today for a new RTS game, then the distance between SC1 and SC2. There's been no new Warcraft either. There's very little happening at ABK because all their money is on COD. It's a single basket strategy that allows them to stay alive, but they have no game plan for when COD falls out of relevance, then what? How will ABK course correct with nothing else supporting them? It would die out and someone would have bought them out anyway, which is, imo, what you're seeing.
The reason why you're seeing such support for MS taking over ABK is because there is a very large and loud and disappointed PC population that doesn't exist on the console base that wants MS to take over Blizzard and bring it back to what made Blizzard great to begin with.
