Must. Play.
Gameplay- This is addictive. You can't get anymore addictive than Ms. Pac-Man. To this very day over 24 years after the game came out, I still get addicted to it.
Graphics- The major modification over the original Pac-Man. The graphics are great, clear and easy to follow. Exactly what you want from an Atari 2600 game.
Sound- sound is usually the finishing move of a game on the old-school systems.That's why this game is so great. The lack of in level music and the sound of your munching make this game feel more intense, and the little music clip at the start of each level is unforgettable. Classic.
Value- As if I haven't stressed it enough, this game is addictive. You will play for hours. Try to do an online search for the high score in Ms. Pac-Man. Then try to beat those scores. That's value.
If you own a 2600 and are retarded enough to not have a copy of this game you need to get it. Or you will die.
