It would be nice if the game isn't so straightforward like 'this is the good path where you get all the girls and this is the bad path where you get cucked'. For example, I would love to have Ian get both Lena and Cindy or Cherry. But Lena has a bad history of being cheated and wouldn't be so keen of having yet another side bitch in a relationship. Cindy also isn't the type to be in a polyamorous relationship, especially if she has to share with another girl (Cindy's a taker not a giver). So for Ian to end up with them both, Lena would also have to cheat like maybe with Axel. That way, Ian can call out Lena for her hypocrisy if she gets angry with him for cheating with Cindy. And so Lena wouldn't feel so betrayed by Ian's actions and might be willing to have a poly relationship. The same goes for Cindy. She might cheat or her relationship with Wade gets resolved in a way that would make her be open to sharing Ian with Lena.
This way, this 'good ending' wouldn't just be a simple 'good path' and there's actually consequences involved to reach it. I really hope this game have this depth and isn't just a simple black and white that I see a lot of times.
