Without a doubt, "Donkey Kong" marked a big moment in video game history. It was the first ever video game to have a story, and it introduced us to a carpenter named "Jumpman" (soon to be known as Mario of "Super Mario Brothers" fame) who had to save his girlfriend from the clutches of Donkey Kong while avoiding enemies like rolling barrels. While the game is outdated by today's standards of video games, it's still worth a playing.
