Return a description for this game instance, in English.

This is shown in the center of the screen below the game name at the start of a game. It should start with a capital letter and end with a period, and can be a bit more verbose than the version returned by get_instance_description_short().

Note that translation is applied by looking up the specific returned value as a key, so the number of returned variations should be limited; ideally just one or two. To include arbitrary values in the description, you can return a sequence of values in the following form instead of just a string:

This will give us something like 'Score 3 goals.' in English

and can properly translate to 'Anota 3 goles.' in Spanish.

If we just returned the string 'Score 3 Goals' here, there would

have to be a translation entry for each specific number. ew.

return ['Score ${ARG1} goals.', self.settings_raw['Score to Win']]

This way the first string can be consistently translated, with any arg values then substituted into the result. ${ARG1} will be replaced with the first value, ${ARG2} with the second, etc.
