For OpenRCT2 to run you must install the assets from a retail copy of
RollerCoaster Tycoon 2. See the following page for more information on
installing a retail copy of the game on Linux:

  https://github.com/OpenRCT2/OpenRCT2/wiki/Installation-on-Linux

Once installed, set the game_path directive in the [general] section of
\$XDG_CONFIG_HOME/OpenRCT2/config.ini (typically ~/.config/OpenRCT2/config.ini)
to point to the location of the retail installation.

For example:

  [general]
  game_path = "/path/to/RCT2"
EOF
}

post_upgrade () {
  _update_caches
}

post_remove() {
  _update_caches
}
