The "quest item" system has been in place since Oblivion, and tbh I've long suspected that it had to do with all the rage you used to see around the Internet from people who started Morrowind, immediately dropped/sold the package for Caius Cosades who knows where, then came back to do the main quest 500 hours later and couldn't remember where they'd put said package, or who they'd sold it to. Oops.
One of the
best quests in Morrowind that I ever had wasnt scripted, it was because of my own choices.
I didnt even know there was such a thing as a main quest at the time, I didnt have internet. I thought Morrowind was just a world to explore and discover. I was only on my third playthrough or so.
I had done the mages and fighters guild and was wondering what else there was to do.
Then I remembered that package.
What did I do with that? It wasnt in my stash.
So the quest was to locate that package.
It wasnt that hard of one as I realised there were only a limited number of merchants I had access to early in the game.
And to be sure, I had sold it to Arille.
That joy, on recovering that package is unparalleled in later games.
It was a wholly off journal quest, no markers no clues even, I had to do it on my own wits, it had a logical solution, it was choice and consequence and I got the reward of tracking the blasted thing down.
I would
kill to be able to sell the dragonstone in Riverwood or kill Delphine for that matter.
At least that sort of thing makes me care about people.
Arille was my buddy after he kept my letter for me.
Riverwood trader guy?
Dont even remember his name.*
* What makes characters memorable is their mortality, in a way.
Kill Eydis Fire-Eye, and be locked out of quests.
Not in modern TES games, now they are 'essential' because its 'a shame to be locked out of quests'.
No!
This is what gives characters life, makes you care for them, encourages multiple playthroughs.
