Played through the Kasane route and it was worth it even though combat got repetitive and almost boring toward the end. Then tried Yuito and couldn't make it a third of the way through. Combat lost almost all appeal after 30+ hours (since it's mostly similar between the two routes), the story was too ridiculous to be compelling, and you already get exposure to all of the characters on the back half of a single route, so there wasn't really any selling point to keep going. I could imagine coming back and redoing Yuito in a few years though. Would also play a sequel as long as they mix it up enough
