My take on war so far is that it can be fairly easy early on, but impossible late in the game.
Not true, I waged wars in every era now, and it's possible to wage war in every era successfully. (Noble difficulty level)
Don't throw your knights against pikemen (and too many other examples to give here).
Dont underestimate the use of barracks and the appropriate civics for extra promotions when you build new units.
Dont underestimate that dusty old Samurai with Combat I, II, III and Pinch promotions, who can probably kill a musketman better than a musketman can.
Don't go to war past the classical era without catapults or other siege units, and USE THEM to totally batter down a city's defense bonus then use them up to weaken all units in a city RIGHT BEFORE YOUR CHARGE! Don't wait after using up your catapults or the units in the city will regenerate.
Don't underestimate the medic I and II promotions! A well-placed Pikeman or Rifleman can help heal not only the units on his tile, but the units on the 8 adjacent tiles too! Keep him just behind your lines so he can heal units as they are attacking the city.
Don't put all your units in 1 stack, or that puny enemy catapult will show you a thing or two right before a cavalry charge.
For that matter, don't build only 1 type of unit, or you'll get your *** kicked to kingdom come when his war elephants come to eat your knights for breakfast.
Don't underestimage upgrading units. Yes, it costs money. What else are you gonna do with that money? Pay tribute to your victorious opponent?
As a bonus, you get to keep all those promotions your units got in the previous wars, which often makes them much more powerful than units you can churn out in your high production cities! (keep in mind untis with more than 10 XP are reduced to 10 XP when upgrading, so maybe wait till they get one more promotion by vanquishing a weakened unit before upgrading it - unless you need that extra firepower NOW of course!)
And finally, very very very important, unlike previous civ games, seriously don't underestimate the value of pillaging! Not only does it give you loads of money (put 4 units in a stack and pillage a town will pillage it down to nothing in 1 turn instead of 4 turns), but you'll also cut off your opponent's resources if you plan it well enough. A few longbowmen with double Guerilla upgrades accompanied by some pikemen with archery and melee bonuses will lay waste to your enemy's iron and copper centers!
With careful planning in fact, you should have a core group of units you build in the ancient era that last all the way to the modern era and get 5+ promotions, waging various wars with the help of newer units and a constant supply of siege units to fuel your city conquests. And thank god for that combat odds calculator which helps you chose the right unit for the right task!
What is war good for? LOADS OF FUN
It's just not the mindless affair it was in civ2
