I remember a game I played on Atari where you shot "something" (cannon or whatever) on enemy fort to kill the king. No idea what it was called but it was my favorite game when I was around 4 years old. xD

I played this game a lot on a friend's macintosh, but I can't remember the name of the game and if it had colors or not. It's so many years ago, can't have been more then 7-8 years old at the time. I've asked my friend on fb if he can remember the name. Like ropa said though, there's been many different versions of it. I've read somewhere that Andy Davidson was inspired by this game when he decided to create worms

Old Memories!
I used to play this when I was kid (7-8 years old). x')

I think Scorched Earth remains the best game in this subgenre.

I got version 1.5 from here just now: http://www.whicken.com/scorch/
