Because of the series' popularity, various developers have created spiritual successor games similar in theme and tone of the X-COM games (sometimes called "X-COM clones"; Gollop also himself called turn-based tactical game genre in general as "sons of Rebelstar" in a reference to one of his earlier games). The level to which they borrow from the original series varies.
