So, I tried to continue the game today after the crossroad choice going with the "All Paths" choice from the mod but it sadly doesn't work out.
I'm halfway through the Halloween party and the different paths just clash with each other in a way that takes all the fun out of it. (And in addition there are the "Cheating" points when having fun with side girls which probably is going to suck in the bad kinda way in the end as well.) And to expect from a mod to change up dialog and scenes so that everything fits again is probably too much to ask. And when the endings come it would probably crumble again.
The only hope I have that the game dev decides, against all odds, to add an all (main) girls path in the end. I mean the setup would be there with the main girls being close or getting closer with each other, being partially bi and experimenting in FFM threesomes. All it takes would be a simple decision.
But until then I'll have to wait and see, which is a bummer. Because the game has such a high quality in renders, writing, scene setup, it's really immersive and interactive and gets you involved with the story and the characters with that one important downside, that we don't get the option to live it out the way we want to (with we I mean me and everyone else who would love to see an harem-style route as an option). And now I'm just going to be sad...
