I'm playing with the version that still does not have the wasted food parameters implemented. When I first learned about the wasted food feature I was like "OMG, I'm going to hate this". But after playing my current game, I have to say it's not bad, actually I find it effective to prevent the unrealistic massive cities I got in my previous game. My biggest city is my capital at size 30 in Renaissance, which I think is not bad, in fact it's more than what I was able to get by the same era in regular BtS.
Anyway this feature has now been parameterized (great), but I just wanted to give you this feedback.
Bye!
