Since Emacs is an programmable editor it would be difficult to find paid project based work based solely on Emacs alone.
The Emacs text editor was first developed at Massachusetts Institute of Technology (MIT) in the 1970s by Richard Stallman and Guy L Steele Jr. MIT is a private research university with a strong emphasis on science, engineering and technology research.
The Snake and Tetris games are built into the Emacs editor. Open the terminal (in the Utilities folder within the Applications folder) and type emacs at the prompt. In the Emacs editor press the Escape key (Esc) and then the X key. This will give you a cursor at the bottom of the Terminal window. Type snake or tetris to run the games. Use the arrow keys as controls. When finished press the Control (Ctrl) and Z keys.

Some may think that the vi editor is too cryptic in its use of commands; i.e. it is not very intuitive in terms of doing edits. Other editors seem to allow users to 'take' to them in an easier fashion. However, if you use it long enough it becomes (like anything else) second nature.
