Its unclear at this stage, exactly how city growth is going to be formulated. What we do know, is that there won't be 'farmers farming squares', but a uniform farming instead. Dependent on how much control we have of growth, that may to some degree prohibit ICS in its current form.
However, all ICS really is, is a player using growth advantages of small cities pumping out settlers as fast as possible, which is especially useful, since small cities grow faster.
I don't want small cities to stop growing faster; otherwise, its pointless to build later on, but there has to be either a limiting factor or a cost limiting the growth at the ICS extremes, that ranges from difficult to impossible.
There is already an effective method in CtP1, that just needs to be toned up, and set for the map size, to prevent ICS already. You can set empire size limits and capital distance penalties. These both affect happiness, in the case of the empire size limit, all cities, and in the case of capital distance, each individual city having its own modifier.
They are set by government, so early government forms can't expand rampantly, without extreme happiness penalties causing production loss and ultimately rioting, which makes the cities an albatross rather than an asset, add to this captured cities adding to the total, and you can make your empire unstable with too rapid growth.
We have had discussion of this in this forum; by one of my posts
More roots of evil and their solutions which was a follow on from a Civ3Suggestion topic. I do believe that the
Wonders o' the world... the root of all evil? thread also ties into this interwoven balance problem.
Ultimately, we need to somehow balance the playing field, for the human and AI, to have a challenging, and hence stimulating and fun game. This isn't a problem for those content to beat up on the AI, and people at the other spectrum can set there own arbitrary rules, like the OCC challenge, which is fine in and of itself, but seems a ludicrous limitation to me.
