It has been called equal to (or better than) "Alien". "Aliens" is credited with expanding the franchise's scope with additions to the series' lore and factions such as the colonial marines; these led to its appearance in other media, such as comic books and video games, and the development of the "Alien vs. Predator" franchise. With its impact on popular culture and fan following, "Aliens" has inspired a variety of merchandise which includes video games, comic books, board games, clothing, music, books, toys, and collectibles. The film was followed by two sequels"Alien 3" (1992) and "Alien Resurrection" (1997), neither of which were as successful. The "Alien" series has prequels to "Alien" ("Prometheus" and ""), and a fifth sequel was in development in 2020.
