I guess it kinda is. Some choices are a bit… peculiar.

I’ve just been using it for so long I have no concept of how it reads getting into it for the first time.

It can also be used as a bit of a behind-the-scenes engine in some emulation wrappers, which I guess sort of works around that issue, but hey, that’s definitely a valid concern. Retroarch makes sense if you emulate a ton of systems and want a consistent experience across the board, and it has some nice shared features across all cores, but all of that definitely comes with some complexity.
