[XBOX360] My Opinion

There are four guilds. There's a thieves' guild quest that can get you in trouble for stealing from some loon in a tower, and I believe there's a dark brotherhood quest that may get you in trouble, too. It's been a long time since it happened, but it sucked. That's why this time, I'm finishing off the other guild quests first, though this last thieves' guild quest looks like it's a whopper; may save that 'till I have more magic.

Oh yeah! I forgot one.

Thieves
Dark Brotherhood
Mages
Fighters

I can't say I had any trouble with any of the missions getting me thrown out of any guilds. The Thieves Guild mission to steal from 'some loon' - as long as you're not seen stealing from the Mages, then you're not thrown out.

Can't think of which DB mission might jeopardise your standing in one of the guilds.

If you do it all correctly, then there's no reason to be kicked out of any of the guilds.

And the last Thieves Guild quest is "mint", as some may say. Brilliant mission.

Actually, now that I think about it, I may have gotten kicked out because I got first strike on him last time, so it counted as murder.

I'm really loving the sneaky/assassin type play. I made my own class called "Ownerer" that is like a assassin/archer/illusionist. It's pretty awesome.
