My bias might be at play. Oblivion broke a lot of what was good about Morrowind but also made some improvements. Skyrim improved on what was better and fixed most of what was broken (spellcrafting being a notable exception). Oblivion does have some great storylines, sure, but even there it’s no better than Skyrim and often worse.

I get that for those whose first TES game was Oblivion it was amazing. But for those of us who’d played Daggerfall and Morrowind it was a let-down, a big dip between Morrowind and Skyrim.
