You know what there should be? My Little Pony, the RPG. (That's tabletop, kids, not video games.)
Anyone who was a fan of the cartoon can hopefully see what I mean. It was FULL of magic and adventure! Demons! Dragons! Ancient mystical cities swallowed up into pocket dimensions! Thousand-year prophecies! Spells gone awry! DOOM!
And also singing and eating cookies, but that's just a sideline.
