Core War is a game about two or more programs written in an abstract assembly language (REDCODE) dueling/jousting/fighting. The goal of it is to get the enemy program to have no more running threads.
Brainfuck Jousting is a Core Wars like game using a Brainfuck derivative instead of REDCODE. It has a bit of activity on the #esoteric IRC channel, but it's very thin. It has an abstraction syntax to make writing programs in it somewhat easier. Its goal is to zero out the enemy 'flag'
Do things like these and their relatives belong on PPCG? If so, how would they be handled and executed? What would be the scoring criteria? How would matchmaking be done?
