Between the Stars, a recent Early Access space action game that looks awesome is coming to Linux, although not any time soon it seems.
Between the Stars is a space action game with RPG growth and real time combat that places you at the helm of an interstellar cruiser. Your mission will be to protect the civilized world from the Children of the Sun, a faction that dominates border planets in the known universe. In order to undertake your mission you must cross the galaxy, face new challenges at each warp jump, and make difficult decisions that affect your ship, crew and the world that surrounds you while upgrading your ship's equipment and fighting in battles to survive.
Funded thanks to people on Kickstarter last year, Isolated Games made it clear that Linux was going to be supported. Although, they never did give a clear answer as to when that would be. They simply said they would work on the Linux version "As soon as we can".
I spoke with the developer now it's out in Early Access to see what their current plan is for Linux support, they told me over email "We plan on having linux support in towards the end of the game's development cycle." so we're in for a wait. I just hope they don't come across any major issues, leaving a port until the last minute has caused issues for other developers who haven't properly planned or even checked if middleware they use actually supports Linux.
You can wishlist/follow it on Steam. At least until then we have titles like EVERSPACE and X4: Foundations to keep us going. For a look at Between the Stars, their trailer is below:
