the answer is licensing/royalties. Similar to how the (early) wii had DVD support, but Nintendo didn't want to deal with royalties, so the feature got axed.
Has nothing to do with royalties.
The fact that pc games are still dvd based is to ensure maximum support, for most if not all pc gamers there is 0 reason to upgrade to a blueray drive just to install game data and run a disc as proof of ownership.
Thats is why pc games are still dvd based, maximum user support.
Nintendo as far as I can recall have never ever paid for rights to use media licensing such as dvd, this is why all of its consoles while having optical media, have lacked the media support.
They are always one step behind using the cheapest hardware as possible, hello how they long it took them to wake up and accept the advantages of disc based media vs very expensive cartridge based media to which they reverted to for the switch.
Which is a massive step backwards in regards to console evolution, the media platform is very expensive to produce in comparison to optical media.
It was the main reason what crippled the n64 and why it failed to gain advantage over the ps1.
That continued over the to cyber, nintendo still refused to pay up licensing rights to use dvd based media and opted for its again restricted mini dvd based media for its games.
Then the wii had to use dvd format simply because it would be stupid in those days to have a basic game on multiple discs when it could be on one dvd discs.
Nintendo don't have to pay any royalties for the use of dvd unless its consoles have dvd media support.
Which any form of the most wanted feature, media support has only ever become a possibility because of the console exploits their legal lapdog work so hard to shut down.
Maybe nintendont should we up, see the needs today from gamers and actually release a good console, not some inferior cheap ass bullshit with inferior bs gimmicks to hype the console.
Pc games would benefit from blueray support, but it also has to tailor to the public, not many pc gamers have upgraded to blueray media which I find stupid as most you see online these days dknt even include dvd drives.
