Here is the new climate map with the terrains we have decided to use: Here are the benefits of the terrains: * Grassland = 1x food production, -10% on defense, normal manpower * Plains = 0.5x food production, -10% on defense, -20% manpower * Mountains = 0 food production, +20% on defense, -15% supply (15% of your whole army dies in these provinces), -50% manpower * Forests = 0.5x food production, +10% on defense, -5% supply (5% of your whole army dies in these provinces until the year 700 BC and tech lvls 5), -20% manpower * Rocky desert = -0.2x food production, -15% supply (unless you've started in the Middle East (European Turkey and above Caucasus doesn't count), -50% manpower * Sandy desert = -0.75x food production, -40% supply (same as in rocky deserts), -80
