Also yes, in the case of collecting, the point is "acquire bragging rights about an old object just because it's an original copy"

If you wanted to just play it you'd just play it in an emulator.

I will point out that the history of video games is not that old in itself, meaning a several decade old game is falling into the "one of the first games made" vintage tier.

It’s fraud also if it’s a forgery, even if the game worked. It was represented as an original when it was sold, not a high quality modern copy.

Yeah, the case of "this is something we knew existed but didn't have a copy of" makes a lot more sense than "I want to be one of 20 people who own a copy of this thing". Even the collectors openly admit to actually playing the games via emulators.
