Video games have worked hard to be seen as legitimate forms of storytelling. Certain franchises like Resident Evil, Mass Effect, and Uncharted only work as well as they do because they have multiple games to build upon their legacy and provide their ideas and characters closure. Not every video game goes into production with hopes or expectations for a sequel or grander series, but there are still titles that conclude with cliffhangers and tease what’s on the horizon.
