Have you tried No Man's Sky? Once you get the initial couple of hours of "game" out of the way, there is pretty much absolutely nothing to do except hop from star to star, land on planets, and wander around them looking at the prettiness. I sunk hours into it. I wish the PS4 version had a cheat I could enter to completely turn off the "survival" mechanism and the HUD so I could just put it up on my projector, find a nice view, and have a living painting on my wall.
