Hey, thanks for the quick reply. I'm looking for a mod (if there is such a thing) that allows you to make multiple decisions “at the same time”. For example, the scene with Linda, Cece, Chris and MC in the bar. You can either take a photo of Linda or Cece. There are mods for other games that let you do both.
No-one's ever done that for this game, I think mostly because the point totals for the girls are less important than the decisions you make (except for achievements, which mods always break anyway). Only things like being able to go with Kira AND go home to Cece might effect the overall game, although again you're risking breaking some things.
Also, early mod for this was made by Sancho, and its older than some of his more recent mods that let you do multiple paths without interfering with your overall play. The only other walkthrough mod that goes to the end of the game is by the dev, so it still only plays the way he wants it played. There was another mod, but I believe it was abandoned after ch. 5 or 6, and it never offered "do everything" options either.
That said, you can't see all the story in this game without doing multiple playthroughs anyway, and there aren't that many this-or-that choices throughout the game, meaning you can pretty much do just 2-3 playthroughs to see all the non-LI-specific events.
If one girl is enough for you, then that's a problem, otherwise just keep track and choose the other options on your next playthroughs.
