Ofc I played Sage route, on my first run just after release. And it was very strong, both her route and the update as a whole. No spoilers, but we got several plot twists, developments and a lot of emotions.
Don’t read reviews after release, it’s the same thing in all games here: review bombing from players who are not interested in the story, who play only for the porn scenes. Giving one star just because mini-games annoy you is certainly not objective. My personal rating from the update is 9/10 and it turned out better than Ep.9. A couple of the new minigames are annoying, no one likes the math minigame because it's designed for a very strong math mind, and the free rooms in this update are well balanced and not annoying.
But all the shortcomings are covered by the story part. So, I highly reccomend to play.
