There is plenty that is DOS/Win95 and PC98 too, on the same disc. Amiga 1200/CD32 are also pretty much interchangeable too outside Akiko. Good thing we don't do floppies, or C64/128 and CP/M would be a mess as well.
This discussion has been going on forever, and now getting into Video and Audio stuff there needs to be something else defined, no intro doesn't cut it. Said that 10 years ago, it's true today. A lot of stuff it just not a tightly controlled closed source product that is easily put into a box.
One mod wants to do it one way, and another mod wants to do it another way, and we're still in the same place with pointless bickering instead of hammering out a solution that everyone can be happy with, or at least tolerate. DJ and I tried to bring some kind of consistency to PC, but that's been thrown to the wind again with all kinds of random whatever defining versions and we're split down the middle about editions being in the name or not.
Accuracy in filenames should be to identify a particular thing, not some OCD thing with perfect naming or caring about how long it is or whatever. It should have some kind of standard, and it cannot be based on information that not all discs have like the PVD date, or Version of the exe, or whatever other non universal thing, and it's only going to get worse with entertainment media. I'd just assume leave them out if they aren't directly tied to a title to function.
There's plenty of valid points from all sides, it's time to figure it out and stop avoiding it.
