Either one of those would work, I just gave two different ones because I didn't know which ones would be easier.Possible? Yes. Problematic? Yes, at least the latter one. The TR movement one isn't so bad, but the other one (the # of TR from a city) would most likely need AI support, which I'd like to avoid).
Critical? Not at all. It was a fun idea and I thought it would make sense for the god of commerce.How critical is it? I'm trying to be lean here - no other functions we can use from the beliefs.xml and/or the belief extensions added by the CP?
Just feel free to put your foot down if you don't want to do it, I'll figure something less interesting out instead.
