I also just started my second playthrough finally, new game (non plus), with both expansions.
Before I started playing, I:
- rewatched TW2 outro cinematics
- read "Matter of Conscience" comics that elaborates on Saskia and what happened in between the games (it was great comic, although very bleak at the end)
- read "Killing Monsters" comics that takes place after MoC, but before TW3 starts and just before the famous Killing Monsters trailer (was ok, not as good as MoC)
- watched the Killing Monsters trailer again - still as bad ass as ever
Then I added few mods to my game install:
Immersive Cam, Immersive HUD, Immersive Motion, Immersive Meditation, Alternative Horse Control
All these make the gameplay more pleasant for me. Went through the Kaer Morhen dream, mountain pass as beautiful as ever..
This is going to be epic journey, again. And I can't wait to get to Toussaint, will be playing that for the first time. The GTX1070 has been well worth the money for this experience.
