A couple of other space games
Strike Suit Zero for those after an arcade space shooter is a LOT of fun. The standalone DLC (can you call it that) is a wave shooter if you want to bypass the story.
Same studio, but under a new name have done Fractured Space which is more along the lines of a MOBA in space, if that's your jam.
Don't forget Kerbal Space Program, or for fans that would prefer more of a simulator, look for Orbiter.
It's not ships, but I wish Shattered Horizon had been a bigger hit, despite my PC being below minimum spec to play it back when that was released.
And if you want some nostalgia, Freelancer is free from myAbandonware (is that legit free? still, it's the second result on a google search for "Freelancer game")
Biting the hand that feeds IT
