Live in the Past or Future + Career Monarchy
I would like to suggest to Alex a game mode in the old world. The Sims 3 had an expansion that made it possible to travel to France, Egypt and China (nowadays). How about, besides an expansion of living in the future, a game mode for living in the past? Ancient Egypt, Ancient Greece, Ancient China, etc, and who knows Mddle Ages? With furniture, clothes, hair, scenery and everything else adapted to the period. Games with this theme are rare. Even modify the game’s “database” with respect to character names, for example, where the player can make a list of names that the characters to be born will have, or maybe a name generator for each period of the game. Also, a “monarchy” style career mode, where the player can have a royal family, whether king or queen (there is a mod for this in The Sims 4, but it’s very limited). This is my suggestion, thanks!
