And not having played Witchers 1/2 I gave up very early on Witcher 3 (mission 4 or 5?) when I got into a long drawn out conversation with some guy who interrupted my bath to interrogate me about stuff that I was supposed to know about from previous games
That was a bit of confusion in your game options. The game developers should have named that option more clearly.
You chose to simulate your Witcher II saves, in other words, you chose to 'feed' W3 with choices you made in W2 so that W3 will have continuity with "your" W2. The 'correct' people (based on your playthough of W2) would be dead or alive, etc. It influences who you meet and how they might react to you in W3. Kind of clever really, but a confusingly named option. I bumbled that one too first time but I figured what the heck, let's go with this.
You could have (should have) skipped that whole interrogation thing. You would have had gone right to our little bowing lesson, said whatever you liked to the Emperor (and not bowed either), gotten the background you needed, talked to your girl, and split.
You might want to revisit W3 at some time. It's a stunningly engaging story as well as a good game.
