Side Scroller Games
A classic genre rooted in arcade-style game design and progression, side scrolling video games focus on movement in a 2D plane from, well, side to side in a scrolling fashion. Codified by legendary games such as the Super Mario Bros. series, side scrollers can have plenty of variety unto themselves, with creativity-focused games such as Terraria having completely different focuses when compared to the origins of the genre.
