That is definitely far more elegant than 2K's clumsy approach of slapping on cellotape to whichever part of Civ V is broken. The only downside I can think of is that some players might whine that it is "unrealistic" or "not immersive" for a civilization to generate less culture the more cities it has.Didn't want to put this in a new thread so I'll post it here. Wouldn't firaxis be better off making the culture-points for new SP always the same, and using a penalty to the NET Culture applied towards the total per turn which is based on the number of cities you have?
So (and I"m just throwing numbers around here)
First policy is always at 100, next at 300, next at 600 ,etc.
If I have one city, I get 100% of culture/turn going towards the SP.
Two cities, 95%, 5 cities, 60%, etc.
That way it seems a lot of the exploits and/or problems with micro people are talking about with SP would disappear. And if properly documented in the UI I think this would actually be easier to understand since people would learn the SP levels for each new policy pretty quickly.
Please tell me if I'm missing something and this is indeed incorrect.
Cheers.
Making culture costs never go down will have undesirable side effects, such as penalising players whose cities are captured rather than sold off, or players who have legitimate reasons for selling off cities (rather than using it as a culture exploit).
Unfortunately, your suggestion probably requires too much work - it is a fundamental overhaul of the SP system. It is probably easier from a programming standpoint to just prevent culture costs from ever going down, and obviously the game designers will want to take the easy route out.
