https://empyriononline.com/ Can do everything as in star citizen. but wayy bigger, more gameplay. just not a "realistic' sim. I got back into it since it has a procedurally generated galaxy, thousaands of points of interest, and a cool mod called reforged eden which makes it really hard, and gives you lots of stuff still to do in eng-game. You no longer overflow with resources like in vanilla. I mean you can do everything. Fly ship. seamless land on any planet, travel to hundreds of planetary systems. go to hangar, drive off your ground vehicle, or launch your auxilliary space craft. Land at space stations. trade is a thing now. missions. the only thing different is it ISNT a simulator, so theres no crashing or crash damage. but everything about your ship is how SC wants to get. Any component destroyed affects the ship. Like generators, fuel tanks, etc.. can even have chain reaction explosions if you don't have a ship with compartmentalised internal components, protected by internal armor.
