answer:Maybe this will help. I recently picked up Elite Dangerous and it’s pretty amazing visually. It mostly involves trading and doing little jobs to earn credits: presumably to buy a bigger, better ship. I haven’t put much time into it yet though. There is some combat (rarely) with pirate ships but I haven’t had any trouble beating them yet. There doesn’t seem to be any kind of colonization aspect though. I don’t think you can even land on a planet. Maybe the other two are more your style. Kerbal Space program is worth a look too. I love that game.
