Terra was the best part of rewrite. Not like that says much, though...
Lesse... If I really were to go into worst routes, I'd just list a bunch of crappy games. There is one crappy route in the most amazing game I've read so far, though...
And it's Kasumi's route in Dies Irae. Why is that even there? Seriously.
Just an osananajimi route where basically nothing really happens. Compared to the rest of the game, it's just plain bad.
To enter the comyu discussion that happened above, I actually had my share of fun with Ayaya's route, but there was one who just pissed me off. Benio! It's even more aggravating because you're forced to read her route first.
She's such an awful heroine that she ruins what would be the saving grace of her route in the end. Then there's the BS with Gasai "changing" that's briefly mentioned so that you can feel her route had some sort of meaning. I'd much rather it didn't and that he stayed in-character, though.
