I have replayed through, and at this point my favorite girls and hopefully become love interests are in this order:
Olivia
Angel
Maeve
Shannon-unless train girl comes along, or any other MILF types in which case she goes down a few notches.. Heck I would wreck Angel's mom's bed before Shannon, though her knife scene did endear her to me. If she were to adopt a bit more edge similar to Angel then perhaps I could move her up.
Maeve seems perfectly aligned to be a main love interest, and is very interesting in terms of her presentation so far. Angel is the classic bad girl from a bad family, and the desire to rescue her is high. Olivia is without a doubt my personal type, and will be the one that if I had to choose an end game at this point in time, and could only have one girl, she would be it. Actually that is what my order represents, again, unless train girl or some MILF or other college girls come along to bump down Shannon. Unlikely the top 3 will change for me!
