Re: Rule request thread

Hello! I'm fairly new to the Game of Life, and I've been playing around with various rule sets in my spare time. I stumbled across this article here detailing a two-player version of the game. It's similar to Immigration/Black&White, but with a few twists to make it more "interesting" in the authors' words. I haven't been able to find much discussion of this "p2life", so I was wondering if anyone else has heard of it, or tried their hand at creating the rules for it in Golly.
Here are the rules for those who don't want to read the article (but I recommend it, it's pretty neat).
Here are the rules for those who don't want to read the article (but I recommend it, it's pretty neat).
The rules of p2life, from white’s point of view (the rules from black’s point of view are
symmetric), are as follows:
Birth. If a cell is empty, then we consider two cases:
1) The cell has exactly three white neighbours and the number of black neighbours
is different from three. In this case a white token is born in the cell.
2) The cell has exactly three white and three black neighbours. In this case an
unbiased coin determines whether a white or black token is born in the cell.
Survival. If a cell is occupied by a white token, then we consider two cases:
1) If the difference between the number of white and black neighbours is two or three,
then the white token survives.
2) If the difference between the number of white and black neighbours is one and the
number of white neighbours is at least two, then the white token survives.
