I am a newbie in emacs and have heard a lot about how powerful emacs is. But the leaning curve seems to be quite steep. If there was a fun way to learn emacs (something like the game VIM adventures) that could help me quickly to familiarize the key binding and modes, I could dig deeper into more advanced features of emacs.
It isn't nearly as gamified as Vim Adventures, but keywiz has points, time limits, and high scores; maybe that's enough to qualify it as a game.
