FDEV is in the unique position to be actively developing a space game, right when this niche becomes more and more mainstream thanks to big titles like starfield / and the controversy of star citizen.
They got the foundation for something that could still last years if maintained correctly. I really hope that they refocus their efforts back on the title that gave them the opportunity to grow to the size they are now.
Base building, new planet types, ship interiors, EVA, more vessels (in space & on the ground), or even a rework of old features. There are a lot of possible directions they could take the game next and the interest in the IP is still quite strong. However they would have to act sooner rather than later.
