Ahh you have to adimre ILS Production's ability to come up with scenarios that allow them to not have to worry about landscapes and large groups of people... a clever way of being lazy, I approve!
Man, now that we're at the end-game of TID, I find myself wishing they would go back and tighten up the entirety of the game... it feels silly having 25 chapters for all (most) the girls, specially considering you kinda need to advance them somewhat evenly to see the bonus scenes between multiple LIs.
All the endings are gonna feel stacked together and it's gonna take away from their emotional impacts... I think it would be better to have more girls depart quicklier... plus a lot of chapters can feel very filler-ish at times as well, so removing some wouldn't really hurt the overall narrative.
Oh well, we'll see how it plays out in the end, but a "final edition" kind of thing could be nice... plus it would be easier to do now that they have all the story beats already in place.
