Hidden command line games!

Hey guys!
While I was searching the web, I found a hidden feature of emacs (for those who don't know what is emacs, it is a text editor for unix/linux. Yup, that means the linux command line.)

Emacs had some programs written in Lisp (a programming language) that had some classic games (like snake and tetris) and some which I've never heard about before (dunnet, anyone?)

To run these games, first go to a linux terminal (for windows, there is a version of emacs: Emacs for windows)

Open emacs by typing "emacs" on the terminal (without the quotes of course)

Press ESC + x

Then type the name of the game to run (eg. snake, tetris, dunnet, etc.)

 Have fun playing!
