This is the strangest RPG ever created I believe. Wendy's has created an entire RPG called Feast of Legends that people can download for free. It's a 97 page long pdf which has the rules and an adventure to go along with it. Wow. The entire game is obviously tongue-in-cheek, but it's actually a fully playable RPG of beginner weight.
There are classes of characters to choose between. There are various weapons and, armor, and items to gain and use. There is a map of the world as well. The items, gear, and world are all based upon humorous adaptions of things in Wendy's restaurants. All in all, it's a nicely done job for a restaurant, and seems like it would be fun to play with kids who like going to fast food restaurants. They will get the humor in the game and probably enjoy it a great deal.
