I had ati card on my pc when pentium 4 was all the rage. I literally spent my teenage years learning english in order to get the dumb games I saved up ages for to work without crashing constantly. Its shocking how the same terrible card manufacturer is part of the company that makes the only cpu worth damn and great gpus.
Elite Dangerous: Best space travel, strap on your VR, put on a virtual monitor playing star trek into your cockpit and stand in awe of how gigantic planets truly are. It has fallen under mismanagement and its mid to late game is terrible. But for the price it’s great.
X4: Space sandbox game from the legendary studio behind… the x series. Fantastic galaxy sim where you can do whatever. Hunt bounties, be poor space trader who converts all their life savings to silicon wafers only to find out nobody is buying them or become ceo of the entire space. Only negative for me is it would be the perfect game if it had open space and orbiting planets and all.
Star Sector: basically mountain blade in space. Not on steam.
Space Engineers: Build your own spaceships and do whatever. The resources are more befitting of an automation game and you can automate.
More niche games: Astrox: Even online but singleplayer. Objects in space: Abandonware that takes an interesting approach to space travel. Delta v: rings of saturn: hardest sci fi space mining simulator around the rings of saturn. Starship EVO: very early access but has the best ship building system I’ve seen so far and ring worlds.
