Thanks to all for the help, some interesting points there. Hi El Justo,
nice to see you. I'd guess that you've probably forgotten more about modding than I ever knew, but I think you must be wrong on this one.
In scenarios like AoI you probably don't notice the city requirement so much because there are so many cities on the map. I certainly concur with your observation on the efficacy of the wonder flag though, it's far more effective.
My experience has led me towards what Heretic Cata and Civinator (Hi guys
) have noted, but I was unclear as to whether there was a seperate flag for requiring a certain amount of cities and the actual reducing corruption flag. I did a little testing in fact, and what I found out was that you don't seem to be able to build any improvement with the 'reduces corruption' wonder flag (like the FP) until you have a certain amount of cities - as the screenie from Civinator suggests. It seems that the amount of cities requirement is linked to the 'reduces corruption' wonder flag, (damn hard-coded flags
) so that any improvement with that flag is unbuildable until you have the necessary amount of cities, though of course you can pre-place them in scenarios.
So, it's a little clearer now, thanks for the assistance all.
