Oh well, haha, you actually already covered or are covering three of my favorite settings, which are Jack the Ripper related stories, medieval fantasy/adventure, and arabian nights. That's why I'm so hyped about Deep in the Forest!
I think the one setting that always belonged to my favorites and that you didn't cover at this point is the Prohibition, in US history. Some of my favorite games are set in that period, like Scheherazade at the Library of Pergamum and The Blind Griffin, and I would LOVE to see a BL game in that setting, for once.
I also teeend to enjoy wartime love stories. You brushed it in the after stories of A Hand in the Darkness, but that was so short!
I think you'd do great with a "proper" sci-fi story set in space, though. The snippet we got in Biel's "after story" for Chasing the Stars was great.
Back to Paul now! I think I got the feeling his personality depends on the stats because of how different he reacts to some things depending on the confidence he has. I still think he's more or less of a blank canvas with a lot of room to evolve though!
As I said, even if Night and Day isn't my jam, I'm still sure I'll like it in the end. It being my least favorite doesn't have to mean I won't like it, so well, I'll obviously be getting it.
And well... I say I hate stat-raisers and I stand by it - I'm glad that type of game isn't as trending as it was in the past, and most romance games don't include stats, BUT I still play these if I like the story, and well, I genuinely love some of them. I mean. I just mentionned Scheherazade, and that one is one of the most difficult stat raisers ever made, it's insane.
