Just to say, but unless you have some diplo reasons, you should consider running environmentalism: you would gain a net 30 commerce from preserves + buro against the 4-5 commerce of a trade route + some gold economy because of corps
Thanks, an outstanding call. Total overlook of my part. No diplo reasons, I did defy everything I didn't like prior to razing the AP and UN. Even I didn't care about too much about the commerce (I had huge lead and my only concern was producing units, overrunning the competition ++ paying the expenses),yet I ran merchants for good amount of time.
