Morrowind had you going around trying to figure out what is happening, whether a prophecy is really about you, convincing varying factions to aid/confirm you, finding out that you are the only one who can stop an awakening god that not even the 3 other living gods can stop and more.
Oblivion has you playing courier boy for a bunch of monks hiding in a fort.
Insert dragons instead of awakening god and you have Skyrim.
Look, I agree that Morrowind is better than Oblivion or Skyrim, but that’s not saying much and they’re still really similar. It’s like the same house with different wallpaper.
Several key things which makes Morrowind different:
1) Structure & predictablity - Skyrim & Oblivion have very much self-contained cut-paste dungeons. Skyrim's were all setup very similar, and you usually ended up back at the start; Obvlivion's all stuck out like a sore thumb as dungeons by the numbers. Morrowind's hand crafted approach on the other handmeant every dungeon you entered - even ones which were similar - felt different, because you just couldn't predict what was coming next.
2) Environments & Enemies - Skyrim & Oblivion again gave us very cookie cutter enemies & landscapes. Morrowind never, NEVER stopped amazing me. A building made from a crab shell, a village of giant mushrooms, just how deep does this Dwemner ruin go etc. Again, because it wasn't cookie cutter, you constantly had a sense of discovery and you never knew what environment or enemy you would encounter next (OK, so you did know about Cliff Racers, but those aside)
3) Quests - All the quests felt very natural & part of the world. In fact they didn't really feel like quests. Yes you went off to help the Blades, but finding your bozz as an old Skooma addict & deciding where to go from there really did make you feel as if you were just living your life in another world, not just running around collecting achievements & ticking off quests.
4) Magic - levitate, breathe under water, boots of blinding speed etc. Again it all felt organic, and very much part of the world. Skyrim & Oblivion reduced that to cliche gaming mechanics designed for console-tards
