Could you add a terrain symmetry setting (ZX/XZ) ? The goal is to be able to generate this type of map with balance opposite spawn.

This type of symmetry is hard to balance.

"--num-to-generate X" to generate X map

An another must have option is "--terrain-symmetry" with X, Z or XZ if you like when the same rating plays directly against each over

--biome DESERT --num-to-generate 3 --terrain-symmetry Z --spawn-count 10 --map-size 640
