IIRC, Imagic was the second? Demon Attack was, again IIRC, their first, and was visually smashing compared to almost anything else on the Atari VCS at the time.
I played Laserblast when I had the chickenpox and I scored one million and all the numbers turned into explanation points. I took a picture but had flash on so it didn't take.
