If we are talking about the same game FoW - I was also very upset about that break up, funny though, when she appeared again I wasn't interested in her as a LI anymore, probably because of my "Ex should remain Ex" thing))
I'll intervene, if you don't mind, but Kristyn from FoW is my favourite ex ever (like Julia from SC is my favourite ever
current), specifically because she and Rex were good together and because her reasoning for the breakup is sympathetic, unlike many other examples who either cheat or leave the MC to pursue career opportunities (I mean, I can respect the latter case, but I don't really want to get back with such a person). She still loses out against Kendra tho.
Anyways, I don't see that much of a problem with current GFs in AVNs - they are rare enough not to become an overused trope, and they present an interesting and hard choice. To me, an MC is not
me, but rather a
hybrid of me and the character he is written to be, so I'm totally fine with him having made some choices before the game's events. In total, I've played 6 games with pre-defined GFs, and I've only broken up with them in 2. In just those 6 examples, the decisions to break up were both easy and hard, and the decisions to maintain the relationship were both easy and hard, too, and they were
all memorable.
Coming back to SC: I can see how having to cheat to switch from Julia to anybody else in the present may seem a bad thing, but the only actual cheating on her so far (
Katy if there was a romance with her in the past) is player's choice and only deducts some points from
Katy if she is refused, not closes her off completely. So, Cap can still avoid "mandatory" cheating without changing anything and have the MC break up with Jules before making the final choice of girl.
One may argue that
emotional cheating is still cheating - well, that thing is part of the premise and the MC's characterization, can't really get rid of that.
