I think there is room for more space exploration games and I welcome other developers to do their own. I appreciate you reaching out like this, but look at No Man's Sky, Starfield and Star Citizen ... there are so many smaller games too. Noctis IV was around for years too.
I think the best idea is to do something unique that does not try to emulate what those big budget games can do. Find a particular angle to focus on and do it really well.
