From Mario Fan Games Galaxy Wiki

Clickteam is a group of programmers responsible for the Klik series of games, including Klik & Play (KNP), The Games Factory (TGF), The Games Factory 2 (TGF2), Multimedia Fusion (MMF), Multimedia Fusion 2 (MMF), and Clickteam Fusion 2.5 (CF2.5). The Games Factory and Multimedia Fuson were popular choices for game development on Mario Fan Games Galaxy. On the 30th of June 2006, Multimedia Fusion 2 and The Games Factory 2 were released. Clickteam Fusion 2.5 was released at some point, and is the currently the latest Clickteam product. You may find these tools as well as others at their site in the External Links section and may also download some tutorials for them at MFGG's site.

Trial versions are available through Clickteam's website, but after the trial period, a purchase is required to continue making games. Also, the trial versions do not allow stand-alone or Internet applications to be created; the games are unplayable unless the player owns the product used to make the game, or you have a friend compile it for you.

The games, libs, and how-to's on the main site were mostly made with Clickteam products until probably somewhere around 2010 (though every lib is made with Clickteam products because GM cannot read or make them for obvious reasons), where in that time, Game Maker became a very popular choice among game developers on MFGG.
