The world I think is gravely misappropriate when applied to game series is "franchise" as it used to specify any name of any game but especially if a game is a series and has sequels, prequels and so on. Franchise as it is, is built on uniformity, standardisation and repetition of the same damned thing over and over again, which I consider to be counterproductive term to use with video games as I wish for my games to be imaginative, unpredictable and highly variable experience.
