 OpenRCT2 allows custom scripts (also known as plug-ins) to be written and executed in the game providing additional behaviour on top of the vanilla experience. This can range from extra windows providing information about the park to entire new multiplayer game modes.

This is usually `C:\Users\YourName\Documents\OpenRCT2` on Windows, or `$XDG_CONFIG_HOME/OpenRCT2` or in its absence `$HOME/.config/OpenRCT2` on Linux.
