Works for me, TT decides the bartergold based on player lvl , and EE does the rest and adjust down. Sounds like a solution to me and I would not have to rewrite my scripts either. So that is a plus, because I svck at complicated script's.
Good

... from an older post about list of NPCs that should be immune to item removal:
That is alot of Boss Npcs etc in FCOM..Are you sure you want this list..Or just Vanilla ones..
Yes, I especially want FCOM bosses. There's not too many vanilla bosses that has special equipment, since quest and scripted items are already immune. But I want vanilla suggestions as well.
Isn't this what Living Economy did, to a certain extent. For example, armour vendors would offer 0 (zero) septims for staffs, but Rindir would buy for the highest amount, and still buy armor/weapons at good rates. So it must be do-able.
Yes, varying prices for an item at various merchants is the main feature of "Living Economy - Items.esp", which can be used just as well together with Enhanced Economy as with Living Economy, btw. So yes, it is doable, but I will not do it until I can think of a better way of doing it than what LE did. LE's implementation suffers from the following:
1. Only works for vanilla items, not for similar items added by mods.
2. Only works with vanilla merchants, not for merchants added by mods.
3. Overwrites any rebalancing of item prices from other mods
4. Somewhat resource hungry - lots of spells added/removed
But I have a vague idea of how to do it really general, so that it will work with all items from all mods with all merchants, and be based on current gold value even if it is changed by another mod. I'll think more about it when I have time.
...about a global economy modifier that is affected by the main quest:
Just wanted to say I think this is a great idea. Not bad at all, very real. I wonder if even after the MQ is complete if this could not kick in again every few months (or even in half -years) or so to represent some other (unknown to the Player) crisis, perhaps political economic concerns elsewhere stuff affecting Tamriel. The -0.5% + facters could be randomised and at some point end for a while. Just a mild thought.
The randomization would be easy to add, but I think I want some good reason for it.
But would any of us play the game that long after the MQ, I wonder?
I do have Verona Houses installed and mean to play it the next time I've completed the MQ. But it doesn't happen too often I guess
