tHIS QUEST UPDATE YOU are working on, how does one integrate
that into ones game, is it even possible or you have to install
the whole thing once again?
Updating shouldn't be a problem, generally. There are a few rare occassions where there could be an issue if you're at a certain quest stage in some quests, but those chances are pretty low, and easy to fix.
A new script is run at the start which adds the new topics for the new quests, and sets a few more NPCs essential, instead of adding it all to the original startup script. That way it doesn't require a new game for the new quests to be added. All the journal entry improvements, extra quest markers and better facial expressions for the old quests will not cause any problems.
There are a few minor improvements to some of the NPCs added by the mod which may not take effect if you've already met them, but they're not very important.
All things taken into account updating the mod from 1.06 to 2.0 should go smoothly for most people. The only extra thing you have to do is if you created the silent voice files with TES4Gecko to slow the dialogue you have to do so again, because of all the new dialogue. Those using the OBSE plugin that slows dialogue don't have to do anything.
I finished testing and tweaking Pride and Greed now, finishing the Deadly Sins section. The Helmet of Greed quest is one of my favourite quests in the main quest.
For the people who've played the mod for a bit , which quests did you like best?
