Building maintenance did a quite effective job of curbing ICS. It did a much better job at that than the draconian corruption punishment in Civ III. The developers had the hubris to throw away a mechanism that worked quite well and make their own. Global happiness is not only a stupid concept that requires amble suspension of disbelief but also punishes the player in a similar fashion as corruption did in Civ III.
You mean
city maintenance, don't you? Just clarifying.
This isn't about wanting cIV per se. It's about wanting a game play mechanic that makes sense and actually works. They effectively dealt with the ICS problem in cIV then threw it all away for no good reason at all. Why?
Moving maintenance to cities and not on buildings worked - so long as every city isn't making more than what it costed to maintain, both in itself and globally. In that sense, Civ IV developers did not, in fact, deal with the "ICS problem." They just hid it a little better.
You still get rampant ICS once you get Corporations, and you get seaside ICS any time you can acquire The Great Lighthouse - literally, every city you found made you that much wealthier. It's not a solution. It's a workaround, and not too effective at that.
Even with city maintenance, it still made the most sense to pack the cities in close - my default distance for Civ IV city distancing is 3 squares, which is only one more than ICS's two.
Civ V
has dealt conclusively with ICS. You can't ICS in Civ V. How? They just banned it outright. You cannot make cities within 3 tiles of any other city, period. It's a blunt manner of dealing with the problem, but in that you can never bypass it, it's a more comprehensive solution.
When you have a good idea or concept, you should either retain it or build on it. Not scrap it.
For example, City States are a good idea in my opinion. How they were implemented in Civilization 5 is horrendous of course. (Vending machines really) If in Civ VI they just nuked the whole concept and left City States out entirely, I'd be critical of that. I am pretty sure that people wouldn't accuse me of "Just wanting Civilization 5.5" though.
Implementation isn't horrendous. Simple, but not that bad. The UN vote is pretty bad, and the way the AIs behave is also bad, but it's probably not as simple as you think it is, because I suspect that you don't really know play with City States as much as you flatter yourself to know.
For instance, did you know that you take a diplomatic hit when you ally a CS that another civ covets? It's a serious diplomatic consideration, and not one to take lightly. It says something about Sullla that he doesn't mention this at all, and then rages when every civ on the planet hates him for his slovenly diplomacy.
I am a fan of good gameplay mechanics and a solid, deep, enriching game play experience. If the best example of those things happen to come from cIV, so be it.
It's not. This is precisely what I'm talking about. You THINK Civ IV is all that, but it isn't, and you then rage when every Civ isn't made in the image of civ IV. Sullla's commentary is biased the same way, so it's hard to take either of you all that seriously.
