So, I've brought this idea up before, and there was a nice little discussion that took place regarding some ideas how to make it work. Since I've been playing the game again and was about to do the main quest (just finishing up with Pax Redoran), I had been putting some thought into this.
Here's a http://i.imgur.com/81Wjz5z.png I made. I whipped that up pretty quick just to get some ideas down, but I think it's a good foundation. I had a few other ideas too, mainly:
- Great House versions of the Main Quest (since they'd clearly have some interest in not letting Dagoth Ur win)
- Tribunal Temple version of the Main Quest:
The later Temple quests involve a lot of crusades into House Dagoth territory, so it'd make sense to expand upon this path
Another thing I was thinking about is, if you're taking the path layed out on my flowchart, how to handle all the exposition, as well as how to handle getting (and curing) corprus. Most of the early main quest missions you're sent on are for the purpose of exposition and leveling up your character to handle the later stuff, but if you're swung right into going to the Urshilaku Burial Caverns, players would probably have a pretty tough time. Additionally, without all the Blades main quest's exposition regarding what the Sixth House is, it would all be pretty confusing to the player character, and new players as well.
So, what are everyone's thoughts? Personally, I don't have time to develop such a mod, but I'll at least keep working on the flowchart in case myself or anyone else does want to tackle this.
