Here's a list of games that prominently feature Ms. Pac-Man that I have:

-Ms. Pac-Man (Atari 2600)

-Ms. Pac-Man (Lynx)

-Ms. Pac-Man (SNES)

-Ms. Pac-Man: Maze Madness (N64)

-Ms. Pac-Man (Sega Genesis)

I didn't know I was such a big Ms. Pac-Man fan! So I guess the only ones I don't have are the ones on Game Boy and NES, unless the Saturn had one. My poor Saturn. It sits there hardly being played at all. I'm wondering whether I should have bought it seeing as how I only have two games for it. I went to Game Crazy yesterday and got some Genesis games, seeing as how I fixed it. I got Klax, Ms. Pac-Man, Ristar, NBA Jam TE and Sonic & Knuckles. I guess next time I go back, I'll see if they have Ms. Pac-Man for Game Boy and NES.
