I used to run a small video game development company, called Amok Entertainment. We published a few games on the Commodore 64, including Pot Panic, Woody The Worm, Zuul, Stormtrooper, Cross It, and a few others. Here are some screenshots of some of those games. Keep in mind, it was the stone age of computers and the 8 bit graphics back then were pretty pixely and low-res. (Think Pac-Man and Space Invaders.)
