I've mentioned this game before. Essentially a roguelike version of the old Starflight games, complete with space combat and planet exploration, mostly by one man. This was the guy who made the mistake of publishing through Shrapnel Games, who listed the game at an absurdly high price with limited # of installs phone-home DRM. Years later he regained control of the IP and self-published through Steam and found huge success selling at a more resonable price DRM-free.
He just released the 1.9 UI overhaul patch and the game is MUCH more playable now:
Remember this is a true roguelike, not a roguelite. Kinda like Tales of Maj'Eyal in space.
