so the character i have in morrowind has almost reach a full year and the only quest lines i have actually finished are the raven rock quest line and the tribunal main quest line.
i gotten hellaz far in both the fighters and legion quest lins but never finished them before the only other quest lins that i've ever finished in morrowind was the main quest line nd bloodmoon main quest line.

Good for you!

I've been playing the game frequently for over 5 years, and haven't done half of the questlines yet. I didn't finish BM, never touched Redoran, stopped a couple of missions short of completing Telvanni, only did a tiny fraction of the Imp.Cult, only did the Alma side of the TB MQ, and never got far with TG, or even started the Morag Tong (found them by accident, though). I seem to recall doing or at least starting a Daedric quest involving a "fork" for Sheo, and got the "Star" from Azura, but nothing for Molag Bal, etc. On top of that, most of the factions have more than one quest-giver, so there are a number of quests that I haven't experienced, even for the factions I finished.

Nothing unusual about that, apparently, as there are still a fair number of old veterans of the game who still play it regularly, but who have never even done the MQ.
