Video games and anime go hand in hand. Both mediums rely heavily on engaging art styles, and often use visual storytelling to further their narratives. On top of that, many anime fans are also avid gamers, and popular anime series regularly receive video game adaptations.
Given their similarities, it's no surprise that some video games have already been converted into anime series. Mega Man, Kirby, and Sonic are just a few of the franchises that have spawned successful shows, and some fans are probably most familiar with the characters' TV amalgamations.
Considering the success of these shows, there are plenty of other video games that should be anime. As is evidenced by Netflix's Castlevania, even relatively obscure franchises have the potential to rope in large audiences. With this in mind, it would be exciting to see more Western-developed games — such as Overwatch — receive anime adaptations. Popular franchises could reach a wider audience by offering a corresponding anime series, and fans of the original games would surely appreciate the extra bits of story.
