I'm a librarian who loves anime, manga, and reading a wide variety of genres.
I doubt this would be nearly as interesting if I had the ability to play any of the games, but, since I don't think any of those are available in English, this makes a nice substitute.
I'm amused at the way the game designers bent over backwards to keep most of Alice's possible love interests from being over 30. I mean, age ranges are given and everything, but the math doesn't work out. For example, Ace is listed as being 12-14 years old as a child and 23-26 as an adult. Julius is 24-27 years old when taking care of child Ace, which means he should at least be 35-38 - maybe 33-36 at the youngest. Instead, he's 27-30 when Ace is an adult. I suppose you can explain it away as Wonderland math, but it still makes me laugh.
