Regardless of the development pace, it would make sense if we just had a decision point at the beginning of the game where we had to choose between GW and Filthy (with lesbian being optional in both cases). This way the story would be developed in a very different way for each route but with both being interesting.In the end I can totally see the GW path being superior to the Filthy path. The trouble with AWAM has been that through its slow development many players drift towards the filthy path just to get some content. Yes, there is sex on the GW path and I don't want to discount that, but I think we would all agree that in real-time the Filthy path has more content. If this game were complete, I would probably be playing it very differently.
I know it would be less flexible, but it would close the eternal discussion about who's filthy/lesbian, the player who's made a specific decision or Sophia once the train is on and there's no way to stop it.
Right now L&P seems to be prioritizing the filthy/lesbian routes probably due to the pressure of the patrons, and it has its consequences on the gw route, as expected.
