I recently won a domination victory with Babylon. But I noticed something... In Civilization V, even if your units are 2 eras ahead; they can still struggle against weaker units. For example, I was trying to take Venice. Venice is still in the industrial era and has a few Riflemen. I sent in 2 Infantry and a few artillery. But I still struggled to take the city, even with much more advanced units. Overall, war is unrealistic in Civilization V. I've seen Crossbowmen and Pikemen survive an artillery shot. The most unrealistic aspect though, is how much damage cities do. Realistically, a renaissance era city or industrial era city would do little to no damage to modern Infantry. But in Civ V, a city with a cannon and a few Riflemen, is enough to fight off modern Infantry. In real life, a city with renaissance or industrial tech would stand no chance against a team of Infantry and Artillery. Can you honestly imagine a renaissance era city fighting off Infantry and Artillery? No, but in Civilization V it can happen. It's the same with bombers. In real life, a Crossbowman would stand no chance against bombers. But in this game, it takes a few bombers to take down a Crossbowman. Battleships too. Why does it take 3 shots from a Battleship to take down a Renaissance era naval unit? So my question is, why is war so unrealistic in Civ V? Why are units 2 eras ahead so weak against less advanced units?
