The information in this article is for Terraria v1.0.6.1.

The Main class is resposible for coordinating all the other classes and making sure they play nicely together. Since this class is the core of the game, changing any of the values could produce profound changes, including causing a game crash. That's not to say you shouldn't use this class - you should just be mindful of how your changes will affect things. Currently the only methods and properties that are accessible are the static ones (being that main doesn't have an object instance).
