Tie weather effects into the game via color blocs, so every month reset RNG for every color bloc to generate weather patterns that can result in positive or negative bonus' for the nations on that color bloc, some patterns can just be completely normal weather that don't do anything and are just neutral rolls. It's basically akin to seasonal effects of sping/summer/winter but for color blocs. Just something I thought might be fun and decided to post it on a whim since you pinged us for feedback.
