Different flavors for different people obviously, nothing wrong with that. But yes, unfortunately what I call the "trained" ending, with him being used but escaping is essentially the "middle" ending depending on how you look at it. Pure obviously would be no captures. But I suppose middle is debatable, because maximum corruption leads to the trained end, whereas SOME corruption either leads to the ordinary victory, a temp defeat and then the ordinary victory, or a full defeat where he doesn't leave the island. Thematically though, I tend to think of the trained end or slutmode end as the middle path.
What were you looking for, more specifically though? You don't have describe specific scenes or anything, just broadly what were you imagining as the ideal middle way? What would it look like? Obviously not going to change this game, but I can always consider ideas.
