I was disappointed you can’t use the Detailed Map Tacks for Civ 7 in your PYDT games because the tacks are visible to all players. But instead of waiting if and when the author of that mod decided to adapt the mod for hotseat mode, I decided to do it myself. I modified the original mod to make it usable for hotseat games. You can find it here: Steam Workshop::Detailed Map Tacks Hotseat You only have to disable the original mod when using this mod. Now you can place your map tacks, and you are the only player who can see them.
