I bought Democracy 3 from Positech/direct. At times, before going to the main menu, it auto-detected to make sure I was running the latest version. So, to update to the latest version, we should not have to re-download the full installer… right?
Maybe I’m wrong but I don’t know well Positech auto detection. However full installer it’s only 100 MB. For Gog I’m sure that the user should redownload everything.
