I did vote for war.
I might have misunderstood the poll question at first, but in retrospect, I still agree that war aspects are important to my game experience in civilization even when I play a 'relatively' peaceful civ. I'm primarily a 'builder' at heart, but I do enjoy the options that military strategies open up. I'm by no means one of the 'experts' at conquering the world on the divine setting, I usually play on Empire, and often find my country (usually Germany

slipping behind going through the middle ages, as the nasty AI's all seem to conspire against me! But I take heart when my first cavalry units start riding out to deal harsh wakeup calls to my closest neighbors... If I can get a leader or two out of the deal and rush build some late middle ages or early industrial wonders, great! I dont usually use war as a path to victory though, but more of an extension to diplomacy. If I play my cards right, build an alliance against a powerful neighbor, take a few cities and survive my 20 year war contract, I can sometimes make a quick comeback from obscurity. Additionally, the tactics in an extended war can be challenging and rewarding. Using chokepoints, slashing enemy supply routes (roads/railroads/naval blockade), amphibious assaults, combined arms attacks (artillery/infantry/cavalry), and capturing enemy workers. All of these aspects enrich the game for me. I would therefore like to see more of all of it:
Unique units (maybe one for each age with each civ?) would be neat. How about 'renting' units to another civilization (as mercenaries.. the 'lessor' would assume the risk, while the 'lessee' gets to move the units for X turns after paying for their service). I dont like the idea of outright selling a unit to another civ, but maybe military aid would be useful; Gold tradeunits that would be earmarked Only for military unit or building purchase and/or upgrading. You mentioned special bonuses vs other units.. how about receiving bonuses also from stacked units? New unit: General/Admiral - Special ability to add +1 to a military stack's movement or attack or defense once per turn. All ranged units (any infantry after the gunpowder invention) should have zones of control I think. All ground units should also get bombardment with the invention of rocketry (TOW missiles/stinger AA missiles).
I usually play the double your pleasure mod, which has Tons of extras like these. I hope that when CIV 4 comes out it isn't just a rehash of the earlier games with improved AI. That seems to be all I read about on these boards, some folks will give up everything else as long as the AI is on par with Deep Blue!
Anyway, that's my two cents.
