When I saw your title, space combat games are immediately what came to mind.
I adored the space operas that were FreeSpace and FreeSpace 2 (VIP Volition). I would love for something along those lines. Add in a little bit more management, some rpg/progression elements, even pilot/FPS sections, and it’s dream game for me. It’s one of the reasons I was so excited (and let down by) Star Citizen.
