In 1977, after we were all bored to tears with Pong (how lame was that), we were introduced to Space Invaders. This took off like wildfire. I, myself, didn't care for S.I., but I was definitely in the minority. I'm not sure if the screen shot on the lower right was the arcade version, I think it might have been the Atari home version, but basically it was the same.
S.I. was okay, but it didn't even come close to PacMan, but that's just me....
