I also agree that the upload rules feel extremely restricted compared to past rules. I still don't see why we even have some of the rules up. There has been debate that "It doesn't fit era's theme" or something but like, does that even matter at this point in a game with like doll costumes being sold at shops or like futuristic stuff.
They really need to bring back the old upload rules, that way players can show off their creativity more. One thing that makes era fun is the customization, so having it all so restricted just takes away the fun and creativity from players.
