CoD Warzone was a shitty try to do it themselves. It failed.
Main mobile Cod is Cod Mobile (made by Tencent), not Warzone and it's doing just fine.
Oh okay, I didn't know there were two mobile CODs. I thought Warzone had done better than it did, but guess not :/
SIE has literally zero expertise in mobile games. As a result - they would be even more "successful than Concord".
Mobile market is competitive and those who has no clue how to do games there don't survive for long.
Well, Aniplex (also Sony) do have mobile experience and they're successful in that space. If Sony Corp had the synergy among their gaming units that they should've had, they'd of had SIE and Aniplex work together so the latter could enable the former to get up to par with some mobile dev. Or even just expand Aniplex a bit to do mobile-specific adaptations of select SIE IP.
SIE could definitely be further along in that space than they are now, and I don't think surviving long-term in mobile space is really a necessary for primarily non-mobile game platforms. It's just a periodic cash flow for them, and if it stops working? Pull back, and continue as normal. But I think that only works if the company hasn't screwed up their main studio devs to juggle mobile dev internally.
No. They performed from poorly to very poorly so Nintendo pulled out of mobile market. The only reasonable success was Pokemon Go in which Nintendo had a not that much share (they have to share revenue with Pokemon company and Niantic)
But Pokemon GO! is still partly Nintendo, it was a mobile thing, and did very well in that space. Same with the current mobile card game. I was also under the impression the Mario Kart spinoff did somewhat decently as well.
What I like about Nintendo's approach is, they didn't bog down their 1P studios with mobile dev, and they didn't outright port their console games over to mobile, settling with spinoffs instead. So they never compromised their studios' dev pipeline nor the software value proposition of their hardware ecosystem. It doesn't really matter, then, if the mobile spinoffs did gangbusters or not: they either do well and bring in some extra money, or bomb and Nintendo shuts them down. Either way, their main pipeline and platform didn't have to compromise anything to engage in the venture.
I simply can't say the same for SIE when it comes to their PC support this gen, as they've compromised both things. 1P studios with no business doing GAAS had games cancelled & those studios have to start from square one on another game (delaying output from them this gen). And the rate in which they've been outright porting their console releases to Steam & even other platforms is making it harder for some to justify buying the console version Day 1 (or in some small instances, buying a console at all) plus making it harder for them to negotiate timed exclusives or especially true (i.e only on PS5) exclusives with 3P.
Is it causing some massive damage right now financially? Obviously not. But it could certainly cause some complications in the future, particularly with a new console gen launch, it's just a question of how big those complications end up actually being.
