On the Tenth Day of Christmas, My True Love Gave to Me: Ten Platforms A-Leaping

"One of the oldest and most integral genres in video gaming is platforming. In the simplest idea, these games involve progressing an avatar through a series of obstacles by jumping from one platform to another. Originating back in the 1980s, platformers are not a pure genre; there is a tendency for other game types to mix in with platforming. For example, Contra gave rise to “run and gun” games; these are a cross of platforming and shooters."– PlayStation Enthusiast
