Video game sequels are new installments in a game series that continue the story, gameplay, or characters from previous titles. They often build on the success of their predecessors by introducing new features, improved graphics, and expanded worlds. Popular examples include Super Mario Bros., The Legend of Zelda, and Call of Duty. Sequels can vary in their approach, with some maintaining the same gameplay style while others may experiment with new mechanics or genres. They are typically developed by the same studio or a different one, aiming to attract both returning players and new audiences.
