My Little Pony: Tails of Equestria is the official My Little Pony: Friendship is Magic table-top role-playing game (TTRPG) created by River Horse Games.
Scatterbrain's Games are "home-brew" (unofficial and self-made) adventures and mechanical modifications for the Tails of Equestria game. You will need at least the official core rulebook of Tails of Equestria to use these home-brews!
The Adventures are written for the Game Master (GM) and contain major spoilers for players. If you want to be a player, do not read the adventures!
