I think you might like Freelancer. All of the models in this are ripped directly from that game, so I can't take the credit for anything that you're talking about. I still love Freelancer's aesthetics.
All I can say is that it should have been made clear on here (it's clear everywhere else I posted about this) where the models came from.
On the "purple sails", those are design element unique to the Japanese descended Kusari ships. All their ships have them to some degree.
