Text Invaders should be easy.  You start with a buffer containing
suitable text.  Set up a timer that runs N times a second
and carries out one move for the invaders.

Every so often you reduce the timer interval a few percent,
so that the game gets harder.

As for the user, you don't have to do anything except switch to the buffer
in a window for the user to edit.
The user's "moves" are simply Emacs editing commands, executed as fast as the
user types them.

Delightfully simple!

The errors don't have to be random.  An invader could move over the
screen, introducing errors.  You eliminate it by moving point onto it.
Then you can fix the errors it has already inserted.

Lots of variations can be imagined.
