A function added by the Fallout Script Extender.
Returns 1 after a game is loaded on a per-script basis. For each script that calls GetGameLoaded, the command will return true exactly once each time the game is loaded and false thereafter.
- If this function is used more than once in a script, the second instance of it will return false. Therefore it's crucial that any relevant parts of the script are kept within a single instance of this function.
