My second character joins the Dark Brotherhood, completes those quests, and yadda yadda yadda.
I have to say, the difference between these two questlines, in terms of writing, length, variety, and overall quality are staggering. One can count the number of College quests on one hand, with only the final quest in Labyrinthian being anywhere near "epic". At the end, you're unceremoniously made archmage (even if you're a burly Orc warrior who only knows 3 spells) and everyone then proceeds to treat you as though you're still the newest apprentice. There are no radiant quests.
The DB questline felt as long as the main quest, longer even. The marks were all detailed, and you could even ask for snippets of advice about every quest before you did it. There were "main quests", misc quests, radiant quests, and at the end you definitely feel like the greatest assassin in Tamriel - and your guildmates definitely respond to that.
So my question is, why the huge discrepency? Why did Bethesda choose to allocate so much more resources towards the DB than the other guilds? In Oblivion, at least, they were all sameish in length, and while some were more interesting than others (again, the DB), I felt like it was just coincidental, and not because one faction was obviously given more attention than the others.
Maybe it's because the DB was a returning favorite? But that's not enough - the College quests were objectively stunted, right?
