You know that the other two words also exist though, right? Like, you can effect change in an organization, and there can be something strange in the affect of a psychopath. So there’s a verb “to effect” and a noun “affect” (although here the pronunciation is different–the accent is on the first syllable). It’s true that the most common usages follow the rules you’re laying out, but it genuinely is an oversimplification.
I wouldn’t really call it a favorite, but I definitely ended up liking Nier: Automata pretty well after bouncing off it really hard when trying it at a friend’s house. That’s because we were trying from the start, and it starts with a section that’s about half an hour long, with only two checkpoints, vastly harder than anything else in the game, and in which the first half isn’t even the same genre as the rest of the game. It’s seriously one of the worst intros I can think of in a video game. The rest of the game is, y’know, a pretty good third-person action RPG.
Does the software have an option for closing the session? Some burning software lets you leave the session open so that you can burn additional files to the disc later if it’s not completely full yet, but many dedicated DVD players will only actually play the disc if the session is closed.
(This knowledge pulled from the dim recesses of my memory, which, like DVD, isn’t what it used to be, so bear with me if I’m mistaken.)
In addition to “format shifting,” which is a well-recognized use case, and game preservation, which is a huge and under-recognized public interest in emulator development, emulators are also used for the development of homebrew software. E.g., there’s a port of Moonlight for the Switch, which lets you play Steam games streamed from a PC using your Switch, letting it serve many of the purposes of a Steam Deck. That’s huge! It would be way less practical to develop this kind of software if you could only test on real hardware. Testing on real hardware is also essential, of course, but testing on an emulator is vastly faster for rapid iteration.
