 * Increase most terrain difficulty for players but make rivers more fordable (needs erosion rework?).
 * Ocean plants!
 * "Relics" with weird sort-of-random effects like Slay the Spire (2)? But I don't like the aesthetic of relics as unmanufacturable by the player and looted from somewhere.
-* Cut-down (small map, most environmental dynamics disabled) RL training mode for combat. Train AI system to operate the enemies competently and swap out the existing control code if some threshold is met.
