Sorry if this has been asked and answered already but I didn't see anything with a quick search but I have 2 questions: 1. if one backs at a lower amount can I upgrade later to get the full license? 2. I know if you bought Worldographer in the past few months you get credit but I was wondering if I were to buy the city or dungeon module for it, before the campaign ends, will I get that special link to discount 2025?
