others like myself as simply saying, in our opinions and views the story might be more intriguing with a harem, or at the very least some possible open relationships.
But what you're saying simply doesn't take any consideration of what's already in the game. You're saying that your view is the story might be more intriguing with a harem. You also mentioned Sisterly Lust as an example of a harem game done well. But how would you fit the narrative in Intertwined to include harem?
That's the problem with a lot of what people want type of posts (not just you, not just about harem or whatever other fetish that people like). It's all about just what they want, and not necessarily what actually fits into the game. For example, if you like kung-fu movies and then start saying things like "it'd be intriguing to see Star Wars including some kung-fu masters from Shaolin temple" or "I wish Harry Potter is a kung-fu master so he can combine martial art and wizardry". Nothing wrong with liking kung-fu, but understand that it doesn't fit into everything.
Similarly here. Nothing wrong with you wanting harem. But at least try to consider how it would actually fit into the game. Do we then just ignore all what happened in the game such as:
1. Layla not happy if MC checking out Elena
2. Erynn not happy with Alexis
3. Having to choose between Cara and Nikki
4. MC is pissed off at seeing Emily kissing Melissa
and so on.
