Fangame Engine
From Mario Fan Games Galaxy Wiki
An engine is the coding for an application, generally one based on entertainment; a video game. On games in MFGG, in especially TGF or MMF, the programmers use this term to relate to the main coding of their game. It can also refer to the whole coding of their game, or seperate sections (player movement, AI (Artificial Intelligence, etc). Engines can either mean a howto that someone has created in which many complicated processes are done or the way a certain thing works in a game. This word derives from the fact that the engine is what makes the program run.
