I became a god in a horror game (It's still new so we haven't met the love interest but even then, it's not romance centred. It's more action. oo i'm a sucker for an overly smart mc.like this gotta be solo levelling levels of smart. i found it so funny when he steals this mermaid guy the sirens are keeping captive in this museum. it doesn't make sense now but just read what's out.)
NPCs can save the world ( Lucien is isekaied as a mage npc in this fantasy game he played in his past life, He now changes the story where he gives every villain boss a better life where they don't get their villain origin story and they form a sort of family. It's so fluffy. I love the character designs. the artist is so diverse too with every1 having different builds and a variety of features. no repeat faces. it's yummy.)
