Then after a week later, I spied upon a Wikipedia article here about the game itself.
The start of the paragraph is what intrigues me the very most. Here's a quote:
Mari0 is an open-source fan-made computer game that combines elements of the video games Super Mario Bros and Portal. The game was developed by Maurice Guégan of Stabyourself, who has previously worked on parody games such as Not Tetris. Mari0 was developed with the LÖVE framework , and is cross platform. The game has been released on Windows, Mac OS X, and Linux, on March 3, 2012 . Upon release, the source code was made available.
The boldfaced text is where it gets me. According to the article, it implies that you can legally create/develop fan-made games based on games developed by other developers, then releasing it as open-source.
So, I have some questions:
- How is it legal? What rules prohibits this?
- If I want to mash Game A and Game B together, both of which are well known among the gaming community, and make it into Game A + B, can I call it Game C, then make it open-source without getting any cease-and-desist letters?
- Am I correct to ask such a question?
