emme: I saw in the "region-locked games" thread that Republique was removed from the store mid November last year.
Only a week later on Steam, it got what sounds to be a very major patch - described as "THOUSANDS OF FIXES", controller support, new content to the game and Japanese language support.
(I can't put the link in my post, but it's in the latest "Recent Updates" section of the game's Steam store page)
GOG did not get this update, the last one is from 2016. I have emailed the game company's support, but I am guessing with the timing there do not want to bring it here.
I guess I should contcat the devs as well since I also own the game.
