It's good if you want to skip boring minigames and grinding, and don't want go blind around the plot playing the game. You'll know if your actions give you points for a girl or another and things like that. If you want to be surprised by the game, and even pissed off sometimes (the dev loves to piss off the players), don't use it.
What's better? Harem mod or play as intended? Which one is more immersive? Also can I enable one of the main girl routes and individual routes at the same time?
Can someone please tell how do I enable harem mod? I downloaded season 3 and I'm playing after an year I've enabled all the path and it's all messed up
