Picked my favorite game so far and figured I'd leave this...
I have a LOT of favorite scenes. ^w^
Looking forward to more.
My favorite tropes, huh? Hoo boy, you opened the worm can. Since I've played all your games and liked so many, this will get long.
Here goes...
Enemies to lovers is probably my favorite. I also like teacher/student and that sort of thing, authority and charge basically. I guess kinda opposites-attract too (Gavin and Kai, Just my Buddy).
My ultimate love interest would be tsundere and bespectacled (Aeron from Nursery, older Gavin), have piercings and/or tattoos (Renan from Pact), long hair (Lance from Prince/Villain), and a twisted personality (Asa from Forsaken), mental health issues (Sam from the Forgive series) or weird hobby (Rapscallions LIs) depending on game type. Weird hobby for a comedy, twisted personality or mental health issues for a darker type of game. My favorite games have some angst but a happy ending, like Mixed Feelings or Prince and Villain.
Even though it's not BL, I actually liked most of the LIs in Rapscallions on Deck. The weird hobbies that want to shoot something, or constantly offer to amputate something make me laugh. Perfect for a comedy.
Obviously, my favorite (lighthearted) game you've done was Nursery, and my favorite character is Aeron. He's like my ultimate type, tsundere with glasses. Gareth is a close second. It's weird but I like opposites like that.
My favorite not-lighthearted game is definitely Forgive my Desires, Father. It's perfectly twisted and dark, but can have a happy ending... Again, that goes back to the authority figure and charge trope, plus mental health issues.
I have a hard time playing it because I get so angry at Gabriel (What if you made a separate what-if game where Gabriel stays a guardian secretly loving and envying from afar?), but in Forsaken I love Asa. I've come to realize how much I like seeing people I like upset (like Asa). In games, I like choosing things that'll show me someone cry or pout; I save screenshots of upset faces in manga too.
Wish you could pursue Theo in Fisherman. His personality is one of my faves.
I really have played all but one of your games. I skipped Rent an Owner since it was more of a concept, but that's the only one.
I probably just shared way more than you wanted, so I'll stop there. I'm an autistic fan that obsessed over your games, so sorry about the essay!
