Originally I wanted to write yet another big rant on why Morrowind is one of the most overrated RPGs of all time. And at the end of the day, the conclusion I reached was this: every single flaw I can think of Morrowind, from how boring its NPCs are, to how boring most of its quests are, to how boring most of its dungeons are, to how boring the moment to moment gameplay is, have to do with one thing. And that thing is its ridiculously huge size.
Morrowind is a 2002 game that is much bigger than that of Fallout: New Vegas (2010), the other "good" open world RPG I've played (for the purpose of this discussion, Gothic won't be mentioned as it is rather small and simply doesn't compare to the freedom offered by these games).
Playing Morrowind, I see my quest log marks around 150 quests completed. That's a lot, but as it is, I'm not even 1/3 through the game's total quests. However, something that constantly lets me down is how boring many of these quests are. How similar and therefore boring most of its caves, ancestral tombs, and Daedric ruins are, all with the same kind of enemies, the same kind of loot that scales with your level (no matter what people claim, Morrowind's loot is hardly "hand placed" any more than Skyrim's leveled loot is "hand placed" just because a developer had to actually place a chest in a dungeon), the same visuals and boring layouts.
Then I thought, "well Fallout: New Vegas' dungeons were somewhat shitty too, but at least they served a specific purpose most of the time, as opposed to serving the general purpose of "this is Vvardenfell and so we need a hundred shitty egg mines, a hundred shitty ancestral tombs, and a hundred shitty bandit caves". And the quests were simply far better as a whole, with more depth, replayability, and simply better written NPCs than Morrowind's. Or, at the very least, NPCs that talked like human beings. But like I said earlier, New Vegas pales in comparison to the scale of Morrowind. New Vegas appears bigger than it is because of its seamless open world: it could be easily translated into the classic Fallout engine and little would be lost (and ironically, much would be gained).
I know many may be thinking "just what is "big" to you?". My answer: anything that comes close to the scale of Morrowind. Has there ever been a BIG open world RPG, similar in size to Morrowind, that was just a quality game all around, and didn't leave you thinking "I've been to this fucking dungeon already, I've done this fucking quest already, I've talked to this fucking NPC already"?
