This one, I'll never forgive my parents for. Fireball Island was an amazing game and it is nowhere to be found in my parent's house. The big innovation in this game is that the board wasn't flat - it was a 3D volcanic island! As a part of this island there were tracks your playing pieces went over as well as tracks that the volcanic mountain god would launch fireballs down! Where these two types of paths crossed your character was in danger of getting hit with a fireball!
The goal was to get the gem from the fireball god and make it to the only boat off the island first. Players were encouraged to be cutthroat as you could steal the gem from other players.
What completely stinks for me is that this game is being sold on eBay for somewhere around $150 to $200! Ugh! Parents!
