ped7g: I did back the SS1 remake at kickstarter, opted for GOG key.. expecting native linux binary.
When they started I think they used Unity and dropped plans for the native Linux version when they switched to UE4. And given bad reputation of UE4 native Linux support, I'm not surprised they didn't bother with it. Look at Everspace 2. it's more Epic's fault than anything. Games developers have more important woes than fixing UE4 mess for Epic.
That said, I also wanted to see native Linux version, but I don't mind playing it in Wine - it works very well.
I'm using Debian testing and have no issue with 32-bit multilib needed for Wine in general.
