So I've been hearing alot of complaints about a lack of quests in factions, such as most of them being composed of about 8 missions. So I don't know the credibility of their statements, but just to put it out there, how long did they feel to you guys, compared to previous games?

Because I know that for both morrowind and oblivion, there were about thirty. So maybe its possible that there are fewer quests, but they are far longer, or broken into different stages or something. Or they're just short.

there is about 12 each for each of them I believe

Extremely short. The Mages guild for instance is only like 5 quests long before your archmage. Afterwards and during there are radiant quests. Some of which can be repeated indefinite, but the actual quest lines are rather short. A whole lot shorter than Ob guild quest lines for example.

Dark Brotherhood is pretty long.

Very disappointingly short. They seem so rushed.

Infinite quests are hardly more entertaining than setting a simple goal for yourself in Oblivion and rewarding yourself via the console.

The question should have been, "how SHORT are faction questlines ?"

ouch, are they at least more complex/ better than previous games?

they seemed pretty short, the companions didn't even give me anything for completing them and i was only able to do one of their radiant story quests(my game is bugged?), the stormcloaks quests were mostly the same thing repeated over and over (take out this fort) same difficulty level of npcs and everything... the dark brotherhood quests are boring and repetitive too although they give you nice gear for joining them.

The gear you are rewarded is scaled to your level. Even the deadra gear you get from the special deadra quests is scaled to your level.

I wouldn't have bought this game if i had rented it first. and this is coming from a long time bethesda fan who grew up with the games. Sorry.

thieves guild is fairly long, Dark brotherhood is short as heck.
