Kanon, CLANNAD, Rewrite…
I have to go with CLANNAD.
Kanon was beautiful in my opinion, and underrated. Every route made me question things about our everyday stuff, the things we take for granted. Kanon made me realize to love the people/things we take for granted, cause sooner or later, you’d loose it. Not to mention how beautiful every route was.
Rewrite was beautiful as well. The fight scenes didn’t help my emotions much, but I found the route’s just horrifying to watch. Shizuru’s route, Kotori’s, Akane’s, etc. I found Rewrite routes to just be beautiful, showing the struggle, and strength of each heroine.
And CLANNAD. CLANNAD was beautiful to me. Every route helped the storyline, even if it wasn’t relevant, you should still tell that it helped the storyline because of what appeared. The routes had to do with family too, which I find beautiful, other than the Katsuki thing, and Kappei. CLANNAD made me feel “Feels” in each and every route.
Now for the others
Air - Well, it was confusing and had too much symbolism for me. I also thought that the routes were irrelevant to to story. Even if they might have been relevant.
Planetarian - Who doesn’t love Yumemi ? I found the storyline as beautiful, but sadly, I found myself bored reading the first half of the story since it had to do more with fixing Gena and looking at stars.
Tomoyo After - I agree with Takafumi. It did teach you how important life was, enjoying life to the fullest. I gotta say though, the music in it was just beautiful. I think it was better than CLANNAD music in my opinion.
Little Busters! - Eh. I found Haruka’s, Yuiko’s, and Refrain the only routes worth reading. Most of the stories didn’t help the plot much.
Little Busters! - EX. I liked, the same routes again, since it was modified, and Saya’s and Kanata’s as an add on. I think their routes were good, expanding more into the plot/route.
Kud Wafter - Haven’t read it. Seems boring, not a fan of Kud’s interest and backstory.
Rewrite Harvest Festa - Not sad. Seems more like a happy add on for a fan disc.
Angel Beats! - It is sad, the overall plot, but I don’t think anyone wants to know all the SSS member’s backgrounds. You’ll loose interest pretty fast if you decide to explore all the back stories. But it did have a good message, for portions of it.
Harmonia - Haven’t played it. The plot seems nice though. Not to mention the ED
Charlotte - Eh. I won’t say too much until all the episodes come out. So far though, it seems like it’ll be very sad, considering if you look at the back stories.
