But I guess divorce would be the point, right? After all, although there is a good wife route, a huge chunk of this game can be about Sophia's relationship with Liam not being a bed of roses and tempting her into all sorts of extra-marital relations and social taboos, and most players are going to do down those paths.
The problem is that the one thing L&P has never included is a decent male character of similar age. Why they haven't done this, I have no idea, because the only choices for people who don't want her to be a good wife are incest, lesbian, and maybe even becoming a submissive to a total d-bag. There are younger guys, but really, why would Sophia leave Liam to be with someone who can't provide for and support her like he can?
There should have been a guy who could fill that role of a replacement for Liam because not everyone who plays this game will be into the genres of the existing cheating paths or want to do the good wife path, so a straight affair path with a mature, stable guy should have been included for these people.
