At least Factorio is Linux native (and maybe even works better, for instance it has autosave without pausing support, and the headless server is AFAIK Linux-only…) without Steam : https://factorio.com/download https://factorio.com/download The only issue is multiplayer, which has regressed with the recently added better compatibility with Steam multiplayer : the big standalone servers work just fine, but you won't be able to connect to most random people's games, because most of them are going to use Steam, will assume that you are using it too, and will not have configured port forwarding in their routers for other non-Steam using players to be able to join them : https://wiki.factorio.com/Multiplayer#Setting_Up_a_Multiplayer_Game https://wiki.factorio.com/Multiplayer#Setting_Up_a_Multiplay... (No idea if Factorio's IPv6 support might help with that.)
