I’ve never played the original Oblivion nor the remaster, but I have sunk a boatload of hours into Morrowind, Skyrim and Fallout 3, and only “completed” them a few times each.

The real beauty of a well done open world game is found in the exploration, not the completion.

It’s also worth noting that the OG fans are grown ups now. I used to play Morrowind for 8+ hours at a time. Now I’m lucky if I can carve out a 3 hour chunk of playtime in my week.
