I am looking into
Kvatch Rebuilt-Finished by Deadly Agent and almost downloaded it. But it's a good thing I read ppl's comments on this mod. Seems like there's tons of issues that never got addressed.
OTOH, I'm not sure if Kvatch Rebuilt is for Renee's game. It might work for Saga's since her game is just after the 3rd Era ends. It would be cool to see Kvatch get rebuilt in stages. I dunno, I'll read about KR next.
EDIT: okay, I think I'm going to try Kvatch Rebuilt with Renee's game, which is supposed to be about 20 years into the 4th Era.

I actually just finished setstaging all the Main Quest stuff via console, so there's no 'Main Quest' in her game. So it makes sense that after 20 years of smoldering ruins, some people finally return to Kvatch to build it back up.
Ooh this is gonna be fun! ... I definitely don't want the pre-invasion bit you're talking about Grits, so I'm going to ask the forums over at Nexus which version is best for me. I'd rather see Kvatch start in a near-ruined state, if possible.
