I am 26 years old now and still have my Battleship game.  My brother and I used to play a lot when we were younger and it was a real exciting game of guessing, logic, locating things on a grid and using various strategies.  The best part about this game is that you can fold it up into it's two consoles and then take it on the road with you.  We filled many hours in the backseat during roadtrips with this game.  It is a pretty easy game to learn and to play which also helps to make it fun at the same time.
