I didn't care for it all that much either. It came out around the time I decided to save up a couple days arcade money and buy a home gaming system....I think nintendo soon became available, before that was just atari.happened upon a pretty bitchen(since we're a bit retro here) sight: http://www.klov.com/ Killer list of video games.
It brought back some memories.
I too was highly addicted to Missle command and Defender(probably my most favorite), but also spent hundreds on these: Berzerk, Vanguard, Zaxxon, Gyruss, Arkanoid, Starcastle, Joust and who could forget Xybots. But for the life of me I can't remember that Boxing game where you were the 3D rough draft, boxing cartoon goliaths who each had their own weakness.....left,left,right, uppercut, uppercut......
