These threads are so constant I won't really delve into specifics as most of them have been covered. But know this. Morrowind is an
adventure. The sheer scale of the world, all the little hand-placed details and easter eggs, it's amazing. Oblivion, even when you've seen one town, you've seen them all. Morrowind reigns supreme in its cultural intricacies and sense of immersion, and it is an incredibly rewarding experience to those willing to take the journey. It does not forgive - you may stumble upon a Daedric ruin and be mauled by Dremora at level 2, you may fail a quest, you may even doom the entire primary plot progression. But that only makes the danger more evident and survival more rewarding. The game doesn't "hold your hand" with quest markers and perpetual quests with no deadlines. The combat system is definitely the roughest transition. But ultimately, Morrowind is a more wholesome and polished game than Oblivion.
