The Hare and the Tortoise introduced me to a whole new series of games called Tales and Games from the excellent publisher Iello. It uses fairy tales to create games, such as Little Red Riding Hood, Aladdin & the Magic Lamp, and The Three Little Pigs. The Hare and the Tortoise, though, was our first introduction to the series and offered a new look at games that feel like they're for kids, but have the ability to completely enthrall an adult. It's a great little racing/betting game.
The other part that I loved was that it fit into my game unit. The students have to write a narrative to go with their game and these games all have accompanying stories. It was really quite nice.
I still share The Hare and the Tortoise whenever I get the chance and several of my students have used it as a Mentor Game and created some really interesting games based on the mechanics.
