28. Borderlands (2009)
Written off by publisher 2K Games as an assumed flop, Borderlands was quietly released in October 2009 in the hopes that it might piggy back on some of the fourth quarter holiday sales. What it did was piggy back right into the cultural zeitgeist and become a monstrous success story, coining the term 'RPGFPS' or 'RPS' for brevity's sake. Gearbox's role-playing shooter took players to the highly stylized, street art inspired world of Pandora. Mad-Max meets treasure hunting in one of the most memorable titles on the list.
