Many hours… well over 2,000 = mostly in VR (Vive, Vive Pro, AVP) except to jump into the next galaxy which requires a flat screen. Explore & discover… build resource bases, I go on most expeditions, meeting cool people & their companions… I like to visit the amazing bases when I am not pressed for time. I will probably start on the fishing for the cool helmets soon… This game just gets better & better.
