I was thinking of a way to make small empires usefull again. In vanilla BTS this was achieved due very high maintenance costs. This is not a good way to go in C2C since more cities mean that you have more of those many "+1 " Buildings. For example, I play a GEM Scenario right now (Deity, Eons). I really struggeled with gold problems until currency. Once I got that, my gold income dropped even more due to crime. But I was able to sell 1 or 2 Techs and got enough money to keep science on 100% without building Wealth for a long time. Now, in the later Classical Era, I have 35 cities (which is quite a lot) and I have a small gold surplus every turn. And I just have 1 Shrine of a religion, which is not very well spread. So bigger is still better... What I want to do is making small empires usefull again. First, what is a small empire? This clearly depends on the map size, I would say on giant it would be smaller than 10 cities. Of course this depends on the techlevel you are, but this can be handled with tech requirements. What would you say? What is "small empire" on smaller/bigger maps in your experience? My first idea was buildings, that work like the Pont De Grand, just reversed: "Requires X or less cities to be build. These building would provide a LARGE Science and Espionage Bonus, like "+100% Science, +1000 Science". They are only buildable once in your empire, so they could be great to specialize your cities. They all could be replaced by an autobuild building that requires "at least 10 cities". Second idea was to go over civics. Many disliked the city limits from civics, but they would be great for this purpose. In some categories, you could add one or two civics that add +10 for every city over 10 cities and give LARGE benefits. Another usefull tag is the "+ in your 10 largest cities." This could be expanded a bit to other things like +10% in 10 largest cities", but this civic could also be used by large nations. I also had the idea to make a building only buildable 10 times in your empire, but this would also benefit large nations. What do you think?
