The D sharing faction has been waiting for all of the ground work laid in the previous chapters to come to fruition and now it seems as if this was all a waste of time.
No, because sharing sex scenes will happen in CH3, and in the future. CH4 will be focused on the girls.
Going through the D only looking-glass will take a great VN and reduce it to just another mediocre game that ended with a lackluster finish.
So if a VN includes your fetish it's a great VN otherwise is a mediocre game? Most fans are D-only fans, so you're saying to them that DMD is a mediocre game?
Numbers don't lie. Ch3 has been in development for a year so far, focused on the male and sharing paths, and very little on the other girls. Numbers for MrDots haven't increased much. If there was a fan base big enough that liked that content, then the support would've increased. It didn't.
Only when Sunshine Love got released numbers started to pick up again, which clearly shows you what most fans like: harem-based games, where you are the only male MC. This seems to happen with all the other games and that's why there's so little MMF and sharing content out there imo.
Not all paths should stay ongoing until the end of the game. I suspect Margo and Cassandra are also getting sacked.
I might be wrong though, but it's still too early and CH4 has not yet started. Things might change in the future.
