Instead of yet another turtle graphics implementation I
wish it added features of PC-Robots:


PCRobots is a programming game written by P. D. Smith. It's sort
of a tank game, the tanks have to fight each other. But you can't
control your tank: It is controlled by a programm you have to write!
The best program wins.

PCRobots is very easy to handle: You can use most (DOS) compilers
to create your robots. Robots can build teams, different maps (with
obstacles) can be used, PCRobots has a graphical display and even
some sound.

You can download the game from here:


and read some of the details in the manual:


a text file.

I did enjoy playing with it in 1998 when I taught a first year 
programming course using PCRobots and Turbo C.
