1. Join all the factions!

2. Do all the quests...

3. From all the different quest givers...

4. At the same time!

5. (extra credit) On Xbox, so you don't have the improved journal and have to reread it from the beginning all the time!

Heh, just a fun little semi-rant at the quest overload I have gotten myself into. I'm having to make written notes and draw maps for quest planning. I love it.

This all literally requires at least 3 different characters to my knowledge! Maybe more?

Well, I meant all the factions you can join with one character. Mine is Redoran, and is in every other faction but the Temple (which I meant to join but haven't yet) and Morag Tong, which is wrong for her. Probably won't join a vampire clan either. Been to Mournhold once but didn't start anything, and haven't been to Solstheim yet, or I could have even more quests at the same time. The real cause of my overload is working for multiple quest givers from the same faction. I've been playing it a ton lately and keep going, "wait, where was I supposed to go next? Did I do that other thing yet? Oh crap, I have to go back to what's-her-face for the reward." Back and forth all over the entire island. I turn to the Morrowind Prophecies a lot to remember where I am in each questline, it's more useful than the journal. But it's all fun. I'm leveling like a maniac and have a huge pile of gold and goodies just from quest rewards.

IIRC, there's a glitch to be able to join Redoran Hlaalu and one other house (I recall doing this with a couple of characters on the Xbox version).
