I’d like to get back into playing video games, but I don’t want to have to sign up for an online service like Steam or Ubisoft Connect.
I love technical sandbox games like Scrap Mechanic, especially if they have a “creative mode” that allows me to just make stuff.
I think you need Steam for X4. At least, that’s the only link they have on their website under “Buy”.
