I never actually owned Fireball Island. But man did I ever want to! The commercial does a fabulous job of showing off how cool the game board looks, as well as featuring the elements that really set it apart from other board games.
Seeing the character pieces, the landscape pieces like the bridge, and the action that the game brings with the fireballs rolling down the mountain really made the game feel like more of a toy than a game.
Not too mention the cool theme of the commercial being something akin to watching an Indiana Jones movie. But with kids. And plastic jewels.
There is an updated version of the game called Fireball Island: The Curse of Vul Kar that boasts a larger island, faster marbles, and full re-designed game play. You can check it out here.
