You can't cherry-pick random examples like that and expect me to respond in any kind of serious way, can you? Let me post a picture of Mournhold's underground, probably the biggest dungeon in any game of this type, compared to some random three-room dungeon from Oblivion. Evidence, bitch! So fucking stupid.
Oh FFS, I linked representative dungeons
and lists of dungeon maps for both games, but you seem not to bother to at least skim through them. Yes, Morrowind had a few huge-ass dungeons but I was talking about
average size of dungeons, which is 3 sequential rooms in Morrowind and a much larger, sometimes multi-floored maze with multiple pathways in Oblivion.
However on the whole Morrowind had much more interesting, long and well-designed dungeons for my money.
Longer dungeons? On the whole? Dude, just take a look at those maps. Morrowind's dungeons are almost always short and banalshitboring with a few notable exceptions.
Oh for fuck's sake, all three games are full of that shit, as is every open world RPG of this type.
Wait what, "every open world RPG of this type"? Did you ever play Gothic?
Using that as a dig at Skyrim and pretending Morrowind and Oblivion weren't the same exact way is true purposeful ignorance on a weirdly massive scale. The painting quest in Oblivion is one of a small handful of "different" ones, which all three games have. Skyrim has the Sheogorath quest, the Sanguine quest, both of which are odd and take you to odd places, and a few more I am sure. In all three games those are the unique ones you remember because most others are the same old shit.
Clockwork Knight pointed out more very well written quests in Oblivion in the above post that I seem to have forgotten. However, in Skyrim I haven't ran into a well written quest in 10+ hours of gameplay, and you know what? If you have to play a shitty game for days before you get one or two well written quests, then maybe the game can go fuck itself, I'm not wasting that much time on banalshitboring crap.
What makes these games fun is lore, world design and exploring both. That's why we call them explorefag games around here. Morrowind gave good explorefag because its world and lore were fucking out of this world good. Skyrim gives decent explorefag because its world and lore are pretty decent, and the better combat makes it more fun for action game fans. Oblivion has a shit world and bad writing most of the time, which makes it disappointing. If you want to defend Oblivion tell me why its writing isn't shit fucking terrible and why its world isn't the most boring high fantasy land I've ever seen. THAT I'll debate you on, not this other stupid cherry-picking bullshit that ignores what all three games are all about.
Skyrim's world
pretty decent? Oh wow you have some low standards. The whole fucking world of that game is either a Nordic meadow, forest or icy terrain, "something that denizens of Sweden see every day" as someone has put it. And fuck your strawmen, I never said Oblivion's world was better but its dungeons and particularly quests are way better than Skyrim's, thus making Skyrim a worse game than Oblivion which was the original statement.
