What's your opinion? Did you wish that they were part of the original release when you installed them? Or are there lots of unnecessary changes? Personally, I'm not a big fan of mods which "override" certain things which the developers had envisioned, unless it's clearly for the better. I'm also slightly wary about the armor changes in the Content Mod. Are there screenshots where I can see the changes?

The only times I played a game for the first time with a mod applied was the Complete Mods for the S.T.A.L.K.E.R series. Would you say that the Quest Pack and Content Mod are similar?

I would be interested in knowing this too. Actually I tried both of them a long time ago, and... well, they did add quite a lot of details and background to the game, however the English translation wasn't convincing, and I stopped plying a few hours in. Maybe it has improved though?

There's also this project http://page.g3csp.bplaced.de/?lang=en , which may be interesting, when it's done.
