So I have not played Nebuchadnezzar. But I am a big fan of the old Impressions games and have been looking for something similar. I checked out the #Laysara demo recently and pretty quickly decided it was the evolution of those games that I wanted. It had similar road proximity rules, but they were better visualized and managed. Building + managing production chains was improved too. I would check out the demo when you get a chance.

(It's not out yet, though.)
