On Rin's route now and her festival segment is better than the entirety of Emi's imo. Think I might actually get some feels from this one.
I think the general consensus amongst us is that Rin's route hits you the hardest, has the most highs and lows, and has the most powerful and resonant finish.
I just finished Hanako's a few minutes ago. It definitely proceeded at a rather languid pace and I didn't find myself fully invested until the latter half of Act 4, when they ramped things into gear. The final confrontation is pretty heartbreaking, but the ending was perfect and very sweet, as Zero01101 said, it felt like WINNING. All in all, I'm glad I stuck it out.
Unless Lilly's really knocks it out of the park though, Rin's is in a whole other league so far. I actually want to go back through it again out of nostalgia, but I guess I'll do Shizune's next.
