I didn't find Oblivion that bad :shrug: a lot of missing details that were in Morrowind, but didn't Morrowind have a lot of details missing that were in Daggerfall.
True, but I think Daggerfall's fanbase was a lot more lax about Morrowind because it wasn't really a step forward or backward - more of a step to the side. Daggerfall had numerous complexities, but also failed to deliver much of its promised content and was, in the end, still a procedurally generated wasteland. The overall scope of the game and the freedom the players were given had been revolutionary and amazing at the time, but not necessarily superior to Morrowind's system. Many skills and factions were lost with Morrowind, and the dungeons were certainly simpler, but whereas Daggerfall pursued "quantity over quality", Morrowind pursued "quality over quantity".
I can imagine for TES fans at the time, even those who liked Daggerfall's system, were amazed to interact with such well-developed characters and discover the intricate, well-crafted locations. It was certainly a fair trade. Oblivion did what Morrowind did in that it removed even more gameplay aspects, but it did not really offer anything substantially new/revolutionary in return. The traps and combat system were a refreshing change of pace, but many felt those would not negate the massive slashing of plotline and skills. It's less of an "Oblivion has less stuff than Morrowind" argument, more of a "what the hell were you trying to pull, Bethesda?" situation.
