Every once in a while I think of the idea, and send
out some feelers in the hopes that I can snag some
programmer into making the game. I've narrowed down
the rules to an amazingly simple (yet expandable if
the game caught on) ruleset.
I recently programmed a game called LifeWar for the server which was Life
with neutral pieces and the ability for players to add a piece each turn to
influence matters. It didn't really work as a game so I never added it.
If you can explain the rules for your Life variant (and a suitable name for
it) I can tell you how difficult it would be to adapt and whether I'm
interested.
