Will 0 a.d. Allow for environmental hazards? Examples Spreading fire in forests (age mythology had this) changing the terrain (maybe random berries spawn, planting forests or leveling hills. Irrigation.. Roads?) Spreading fires across ships for tactical purposes. ( fire ships - light up the ship and hope it drifts into the enemy becoming an environmental hazard, NOT age of kings style). Storms that make the deep sea treacherous meaning if you don't build lighthouse (civ2 reference) your trireme could be lost at sea. I know this is not really going towards pure strategy balance, but stuff like this would in some cases be aimed more at a single player audience like the civilization players. Fire ships are much more multiplayer friendly though It's asking a lot I know, but most of this is just a theoretical stuff you could add if you really wanted to.
