In particular, this is limited by: * reducing the number of neighbors to 8 on a rectangular grid, thus making many useful cluster behaviors impossible, and also rounding percentages but not showing any sign of the rounding * not counting "self" when counting the "how many are like self" percentage. As a result, if everybody desires not to be a minority in their local cluster, a 50-50 population mix will be simulated as all unhappy permanently instead of all happy.
