2. Pac-Man
It was loads of fun to control a yellow ball with a mouth, and make it eat drugs and fruit. Pac-Man could have been a wonderful experience, had Namco not made the inexplicable decision to add villainous ghosts to the game. Ghosts, as you may know, are the restless souls of the dead, and are pretty much the last thing you want to see, especially when you're trying to eat fruit in a maze. Namco only compounded its error by making the ghosts chase Pac-Man and, no joke, try to murder him. Getting murdered by ghosts is not fun at all and ruins what is otherwise an arcade gem.
3. Street Fighter II
Street Fighter II is a virtual vacation simulator that lets you travel around the world to exotic locales like a palace in India, the Amazon rainforest, or a fancy Las Vegas casino. Once your character arrives at their vacation destination, friendly people there stand in the background and cheer at you. Inexplicably, Capcom ruins your globe-trotting trip by including numerous enemies that try to punch and kick you using their martial arts skills. The frustrating control scheme of the game lacks any button to call the police, so you have no way of contacting the authorities for help while you're mercilessly beaten to within an inch of your life. Street Fighter II is yet another potential gaming masterpiece ruined by the developers' baffling decision to include villains.
