Gearbox Software struck it big with its now flagship franchise, Borderlands, first arriving on the scene in 2009. One of the earliest titles to set the templates for many of the standards for the burgeoning looter-shooter genre, Borderlands quickly rose in popularity to become one of its major players. With its blend of wacky, semi-dystopian sci-fi tones underlined with more serious themes (especially regarding its villains' motivations), Borderlands has proved its staying power through three main titles, multiple DLCs, and a handful of successful spin-offs.
