Of course, this list would not be complete without side-scrolling pioneer and best-seller, Super Mario Bros. In this OG iteration of the Super Mario series, ordinary plumber Mario goes on a quest to save Princess Toadstool (or Peach) and the Mushroom Kingdom from the clutches of Bowser (or King Koopa). The game's eight worlds allow for endless hours (200 to be exact) of gameplay, and lots frustration for many gamers.
While platformers may seem simple, this list proves that they are not playing around (pun intended). With the endless summer days, any player would be encouraged to test their skills with any one of these thrilling platformers. And when you're finally finished, you can brag about beating one of the longest platformers in video game history.
