I've tried a game with this mod, but it looks there is still a lot of things to do. First, when loading, many error messages, this is boring of course. Second, the cost of technologies and buildings is clearly too low, in my opinion this must be doubled at least. Third, the reaces without any trait fell behind in any aspect of the game, as I seen in my game. Last, I would change the civics of Final Frontiers, as they are not so interesting, for the most.
Anyway, thank you for your great efforts!
