Nintendo are the most secretive and poorly behaved of all 3 - I don’t have any particular issue with them as I’ve not been a customer for years, but they’re notorious for poor backwards compatibility, suing the ass off emulators and anyone going anywhere near their IP or games (even for satirical purposes) and charge a lot of money for what is effectively a potato in games console terms.
The reason you won’t see such a thread about multi-platform for Sony is you’ll instead see ones that you would have seen on Xbox a few years ago - “games are going to PC too fast” (Spider Man 2 was announced for PC in less than a year) and “there’s barely any first party games on the horizon” (Ghost of Yotei and Wolverine are their only announced single-player games, plus Marathon and Fairgame$ - Xbox has a ton in the pipeline we know of).
As the third placed console, Xbox has to innovate - they put games on PC before PlayStation did, they did Game Pass before Sony announced the new PS Plus tiers, they charged for online with Xbox Live before Sony did (I know, a bad thing but the extra money did really seem to improve the online services of both), to name but a few things.
It’s possible Sony will follow their lead in time - I know it sucks as a fan of the third-placed console to see Xbox take flak for going first on initiatives and for them to have to take the moral high ground and ignore Sony’s bad behaviour (and they can’t be too evil to PlayStation now as due to the size of Xbox after ABK and the general size of Microsoft, they could be seen as being anti-competitive despite us all knowing Sony is the anti-competitive one).
I did think the Series consoles would start the fight back - instead, the PS5 despite not offering much beyond PS4 remasters has carried on the success of the PS4 because people stick with what they know, so Xbox is having to innovate further, partly by making money off PlayStation users (which they already do with old games and Minecraft anyway) and potentially via a handheld, PC stores on consoles or going early next generation.
There’s a chance some of it will stick - maybe Game Pass will have the edge when we start to move to streaming, maybe going early next generation will capture a load of users as “the best way to play GTA6”, maybe the handheld will win hearts and minds, maybe PS / Switch players will love Xbox games enough to buy an Xbox for Game Pass (or use streaming / PC), or the PC stores option make games more affordable and Xbox consoles more attractive to younger players (who see all the streamers playing on PCs).
We just don’t know, and I can see why they’re having to try new things - the console warrior teen in me would still love Microsoft to spend big and crush PlayStation by buying massive exclusives like EA Sports FC, Madden and making CoD exclusive, but the realist in me knows unfortunately regulators would get involved and if it didn’t bring in a LOT of money in return Microsoft’s shareholders would probably demand Xbox’s head.
So instead it’s try lots of different things, see what sticks - and if any do, I bet Sony will copy them a few years later…
