2D platform video games, are a variation of platform video games that were a very popular genre of video games. 2D platformers originated in the early 1980s and in the mid 1990s, platformers made the transition to 3D.
At first, platformers took place on a single screen, where the player would have to overcome certain obstacles. With the advent of Super Mario Bros., the 2D platform games began to introduce scrolling levels, where the players scrolled left to right, with the playable character viewed from a side angle. The character climbs up and down ladders or jumps from platform to platform, fighting enemies, and often has the ability to gain powers or weapons. Later on, the term came to describe games where jumping on platforms, as opposed to shooting, was the main gameplay focus. These include games like Super Mario Bros. and Donkey Kong Country. However, many platform games feature projectile weapons, including the Mario and Castlevania franchises.
Platform games are one of the most well-known types of video game outside the gaming community, which could be the reason games based on movies, television shows, and comic books tend to be of the platform variety.
