I hear you, but its not a real life simulator... its a freakin' tongue-in-cheek frat house romp. If not, the game will get one dimensional really quickly... don't you think?
Not really. The five love interests are characters with several different personalities and motivations. None of the side-girls are romantically with the MC at all. You can even decide not to be romantically invested with any of the LIs at all, instead choosing to mess around with the HOTs and Jade.
* You can choose not to follow Isabella in the library, which locks her as a choice to stay in her house. Even if you do, she makes it clear that you shouldn't expect anything more (yet).
* You can choose to not be interested in Jill at least and just date her to spite Tybalt. Or you can choose to not kiss her, which results in MC deciding he wasn't really into her.
* After 3 whole episodes forcing you to be with Josy and Maya, you can choose to stay friends with them.
* And Sage isn't even looking for a serious relationship at all. For now.
If you go to Derek, he actually asks you if you want a relationship, which you can reply "yes" or "no". That's in stark contrast with Acting Lessons, which forces you to be with Megan to the end, and fucking anyone else as soon as you got serious was considered cheating.
For now, the girls are more or less okay with you dating multiple girls, because you're not in a serious relationship yet. However, when it
does get serious with one of the LIs, I'm not expecting to get away with fucking everyone without consequence. Expecting anything less is what would
actually turn it into a one-dimensional generic porn game.
To me, it's inevitable. Choices will have to be made, and it's best to get ready for it.
