I really wish they would do something about the lack of Steam integration.

Even though Steam integration was part of the Kickstarter campaign: https://www.kickstarter.com/projects/1247991467/planets3/description
Apparently it has been decided it will not be coming to Steam (at least no plans): https://www.planets-cube.com/forum/topic/46

No mention of if the online requirement/DRM which was supposed to be for Steam integration will be removed, or if refunds will be offered for those who backed expecting Steam integration and not some 3rd Party small Indie self-run DRM.
