Just wondering wich one you prefer the most but , I woudl liketo know ow many stps where them? how many quests where they composed of and stuff to do ? one compared to the other?
Morrowind's Main Quest had 19 Steps to it (22 total, one optional quest and another quest designed specifically to allow the player to continue the game if Vivec was dead).
Then again, that's not counting all the quests you have to do for the various factions to be named Nevarine and Horator.
Oblivion's Main Quest had Seventeen Steps to it - 18 all together if you decide to convince the other cities to send aid to Bruma, which in turn also expands the length of the Main Quest.
Skyrim's Main Quest has 18 Steps to it - 19 if you count an "optional" quest.
Over all, having not yet finished Skyrim's Main Quest...I think I'd have to give "Best Main Quest" to Morrowind. Oblivion and Skyrim suffer from "Heroes Are Special" syndrome - NPCs just trust you to be super awesome at everything. In Morrowind, you had to work to just get the attention of the various factions, work your way up through the hierarchy, and even then you aren't "special". The Great Houses especially come across more as humoring a lunatic then honestly believing you are the reincarnation of Nerevar. You got a good build up with Dagoth Ur, the Sixth House was integrated into the game world very well...it all "fit" together nicely. Oblivion just suffers from a generic end of the world plot (Complete with Vast Cult Following never mentioned or worked into the game world very well), and while Skyrim is satisfying on making the game's choices ambiguous, I still don't get Alduin's "deal". Again, haven't finished the MQ so maybe that will become apparent in time, but despite how much I adore Skyrim...
...it feels a
lot like World of WarCraft: Cataclysm.
The Dragons and the Thu'um are awesome, don't get me wrong. But Vengeful Dragon God come to burn the world? Time Jumps? Come on Bethesda...while I know the lore of Deathwing is one of the few engaging pieces of fantasy writing Blizzard has cranked out (Thanks to Richard Knaak), you don't have to be quite this blatant about it.
Honestly, I would have preferred the Dragon plot and the Civil War plot to be flipped in importance really. The Civil War choice is just much more engaging and difficult. The Dragon Quest feels very by the numbers.
