Hi Winston, long time no see![]()
Aye. I've not been around the civ-related parts of the forum much lately, though you can always find me (and most of the old Divine Intervention crew) in the forum games area. You should come join us for a game of Night of the Werewolves sometime.

I agree with your point, but there is a diference between ICS and what you called Infinite unit spam
It was aelf who coined the term IUS, iirc.
And, yeah, it's a very different beast to ICS, not least because you actually have to be able to support the army in the first place, whereas an extra city in civ3 never cost more than the price of a settler.
However, one of my issues with civ4 is that, beyond a certain level of economic development, unit costs cease to be a significant concern, even with a truly monstrous army. Once that stage has been reached, the only reason not to spam troops is one of opportunity cost - you could be building something else instead. But with a military approach being usually the safest route to victory, setting half your cities to pour out troops tends to be the more reliable option.
Although I'd stop short of saying that there should be a hard limit on the number of military units a civ can build (beyond the restriction posed by 1 unit/tile), I really hope that there'll be some disadvantage to cramming a unit into every single space.
