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?
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.
I moved to Emacs mostly, iirc, to get gud and then stayed on it. Still use it heavily. Org mode has been a killer application.
I haven't made it through all of vim adventures, but based on what I have done, I think that a significant portion of what you would get out of vim adventures would transfer to Emacs using Evil mode (or derivatives like spacemacs or doom Emacs).
Vim is a text editor.
Emacs is a lisp interpreter whose dialect of lisp is specialized for text manipulation. In emacs the user interface is incidental to the main goal of programmatic text manipulation.
In vim the user interface is the be all and end all. Which is why vim is now a specialized emacs mode when you need character based text manipulation.
Btw If you try to learn emacs in iphone or ipad, iSH and a-shell both give you an escape key and control-key. Hence no emacs default key mode. Guess I can try boon or evil. But you know just 3 keys or basically 4 is not that user-friendly for newbie.
...you're going to have a bad time.
Emacs is not the hammer that wants to hit a touchscreen interface nail.
