Yeah, it is worthy waiting for the patch (IT'S MIYAKO! She's fucking great!). Jokes aside, the only routes left are most of the side routes (except Ume-sensei's), Miyako and Agave. In other words, most of the main routes have been translated.
Only the ones in the Yandere Translation patch (Mayucchi, Chris, Momo-senpai, Wanko, Ume-sensei, Miyako isn't completely translated). And from what I've played, the first days of Capt's route.
Oh god, I'm such a masochist. Replaying Grisaia no Kajitsu, just finished Amane's route (It's fucked up no matter how many times you play it man).
BTW, during my first playthrough I finished Amane first. And I still regret doing that...
I don't know why, but I always get this sense of accomplishment when I achieve 100% completion. BTW, Capt route in Majikoi isn't completely translated (that includes the names of the characters), only the first days.
