The closest I ever got with vim is with this game: https://vim-adventures.com/ How different is Vim and Emacs' user experience? Would the vim-adventures also apply to emacs?

I don't think there's anything like that for Emacs. At least, I've not heard of it. I mostly learned it through reading stuff like Mastering Emacs and watching YouTube videos, as well as testing out other peoples configs.

UX wise, it's pretty different but I know a lot of people use Evil (https://github.com/emacs-evil/evil) or something similar to get a more vi like experience out of Emacs. If you're not vested in an Emacs workflow, or don't have one at all, I think it's worth checking out other peoples configs.

The biggest benefit of Emacs is that you can do some much from one place. That's much less context switching that you have to do, and I can see why some people prefer it.
