I'm one of those people who have tried many different versions of the game. PS3, PC vanilla, PC Special Edition, PC with mods. I actually love Skyrim VR too. But despite all of that, it's never topped Oblivion. I don't know what it is, perhaps it's because it was the first open world game I really got into - whether it be the main or side quests, the graphics (at the time). I felt completely immersed when I played.
There's a third world, the world of objective contents of thoughts. Teilhard de Chardin calls this third world the "Neurosphere", that is, the world of the mind.
