If I wanted to replay chapters 8-11 and onward up to a dozen times, I wouldn't have mentioned my desire for a mod merging playthroughs.
This game is awful for replay value. As soon as you've done your first DIK/CHICK run, you've seen 95% of the content. Why would any player want to redo the same conversations, the same minigames, the same freeroam sections, over and over again, when they are practically identical from playthrough to playthrough?
It's not fun to redo all this shit, playing for literal hours, just to get 2 scenes more. Hence me mentioning how nice a route-merging mod would be.
You are trying to fix an open knife-wound type of problem with a bandaid type of solution and trying to pretend that it's a fix that works just fine.
