I have created a Steam curator that lists all known Danish games on Steam, so as to make that easily accessible information:
https://store.steampowered.com/curator/40000720-dkgame/

The list is derived from the list we maintain internally at The Royal Danish Library, as part of our efforts to ensure that we collect and preserve all Danish video games, so if you notice a Danish game on Steam missing, please get in touch with me.
Due to the way that the Steam curator functionality works I also had to create and attach a Steam Group:
https://steamcommunity.com/groups/spilindustri
I'm not quite sure what to do with it yet, but it could prove useful I suppose.
