Castlevania. Fun idea if the display graphics evolved from NES-style pixel art to current day 3D renders as you progress through your quest modes/defeat bosses.
Maybe not on-brand for ‘spooky’ but Bomberman (look at Saturn Bomberman era for visuals/music).
Lastly, I’d buy a Pokemon pin in a heartbeat…so much potential for evolving your character’s Pokémon along your journey of quests, capturing Pokémon (gotta catch em all), battles and gear galore! Gaahhhh!
