Pastiche

n much current usage, the term denotes a literary technique employing a generally light-hearted tongue-in-cheek imitation of another's style; although jocular, it is usually respectful (as opposed to parody, which is not).

Quentin Tarantino uses pastiche often, as his movies are rarely original works of art; they are copied from sources such as pulp novels, blaxploitation, and Chinese kung fu films. The same definition applies to Hideo Kojima also.
