I enjoy me a good complicated game. Some catan, some alhambra, some war games, and a whole lot of Dwarf Fortress and factorio. I have very mixed feelings about this game.
The game itself is good. Sure, some of the ai trades are a little wonky, but that's an AI balance thing, not necessarily a reflection on the design of the game itself. The art and styling is gorgeous, very Hermaeus Basch, and with some tinkering I even think this could be adapted for live tabletop play pretty successfully.
I'm a big believer that games as pieces of software should generally stand on their own though. Part of my criteria for this is going in blind without reading anything beyond the jam description and while your game stood up on a lot of fronts, it fell just short there.
I know it's a jam and things get left out and honestly? It's one of the only hangups I've got about your entry, but for a game this intricate, instructions are nearly as critical as the game itself. Even just what you wrote in the comments on a static little menu somewhere would have made all the difference.
Taking off my critic hat for a moment, this is good work. For real though, I go in blind because I know as a developer that it's what most people do when they play a game, but this is a solid ruleset implemented solidly. I hope you don't take my hardness for dislike.
