There seems to be a "playing too much", sometimes a "anticipating too much" and a "has taught us" 1000 things for each Civilization game. 1. The world is divided into hexagons. 2. An archer can shoot an arrow tens of kilometers. 3. Early cannons could match archers in range. However, modern tank cannons, despite having a longer barrel, advanced targeting systems and better ballistics, are shorter ranged than those early cannons. 4. The Battle of Constantinople and other famous sieges couldn't have happened; an archer and another unit can't both fit in a city! 5. Armies can replenish their numbers in enemy territory. 6. Contrary to what science says, apparently clouds are not formed by water vapor condensing; they're in places where people haven't discovered yet. Apparently at the dawn of civilization the sky was filled with clouds. Amazingly enough crops and plants somehow survived. 7. The great wall apparently has a magnetic or gravitational force field that slows down modern armor when they're inside the great wall's territory. 8. An "immortal" many miles away from home can somehow replenish its numbers twice as fast as usual. 9. Knights don't need iron. 10. Longbowmen outrange modern artillery.
