Back in the 80s', the Atari was like the playstation. It gave players the ability to play games without going to the arcade. There were many versions of the Atari, including the Atari 2600, including many arcade games. Even though they weren't as polished as the original arcade games, they were fun as hell. Though, Atari had to be mean starfishs and bring us a crappy port of Pacman. I'm not even raging because it was from the 80s', it just sucked.
This game had numerous flaws, like the flickering ghost glitch, where the ghosts would flicker all over the map and kill you. Don't even get me STARTED ON THE SOUNDS! THEY WERE EAR RAPE, TURN THE VOLUME UP TO 3 AND YOU GET "BEEEEEEEP BOOO BEEEEEEP BEEEEEEEEEEEEEEEEEEEEEEE BOOOOOOOP." and it was visually ugly. Pacman didn't even turn up or down, only left and right. Most of the commercials were false advertising, so a ton of people bought junk.
When people were tired of junk, Ms. Pacman for the Atari came out. It fixed most of the problems that the original Atari Pacman had. So people threw away Pacman and got Ms. Pacman, then Jr. Pacman.
