Donkey Kong was the first Mario game which was ever created. It was invented in 1981 and it was amazing for that time. You might think "But Mario's name is Mario!" but Mario's original name was JumpMan. The aim of the game was to get to the top of the slopes, avoiding the barrels and fire coming down the slopes. If you got to the top you would go to the next level. I think there were ten levels in all. And all the characters were JumpMan (now known as Mario), Princess Toadstool (now known as Princess Peach) and Donkey Kong, who hasn't had a single name change. There's four games in all that feature Mario trying to defeat Donkey Kong. The first one is the original Donkey Kong that we're talking about, but there's also Mario Vs Donkey Kong for the GameBoy Advance, then Mario Vs Donkey Kong - Mini Land Mayhem for the Nintendo DS; also Mario Vs Donkey Kong 2 - March of the Mini's, also for the DS. This is all you need to know about Donkey Kong.
