Advent Sinners is a pretty ambitious title with a huge amount of characters and scope. Stats stolen from the store page state:

· 7 Books;
· 5,500+ Illustrations;
· 80-song Soundtrack;
· 40+ Main Characters;
· A 2,000,000 Words Storyline.

I've always been crummy at knowing how many words two million is though. books don't generally have wordcounts. The game seems interesting because it has RPG stats which implies a battle might occur at some point, but I'm four hours in and nothing like that has happened yet. That doesn't mean it won't occur, though! Also it doesn't seem to go for the traditional "routes" of dating sims where just one dialogue choice chooses your path. You get asked loads of questions to get a much broader assessment of the kind of person you are and the sort of choices you tend to make.
