Once when I was a kid I visited the 1982 Worlds Fair in Knoxville TN. The exhibits were nice, but all I was interested in were all the arcade games from far and near. One game in particular I enjoyed playing was a video game that had a ship you maneuvered around sinking other ships with your cannons while collecting treasure chest. Does anyone remember this game?! I cant find anything about it. I'm I going crazy in my old age? Please help me!!
