I imagine this game as taking place in a bizarre dimension, like Xen from Half-Life. Gameplay involving exploration, searching for objects of interest, researching new tech, documenting novel life forms and base building. Perhaps having a lab on Earth with a portal you travel through to get to this realm (like Out of This World) only the portal closes one day and won't re-open
