Laverre: Perhaps he just takes the whole "Triss" part more seriously this time.
That's how it seems to me, so far. All the sex and trading cards in TW1 was a novelty. I found myself accomplishing most of the "conquests", but it didn't really add to the story line. To me, it was more humorous than anything else.
Frankly, I don't really care about sexual encounters in video games. I'm more interested in the story line, and usually the sexual encounters don't add much to it (TW1, ME1 and 2, KotoR).
