A meta game can also refer to a game applied to a game. A tournament is an example of a meta game. The tournament has its own point structure and is a winnable game unto itself regardless of what game is being played in the tournament, e.g. a Halo, Starcraft, or Street Fighter tournament.
Meta game has also been adapted to talk about strategies in a game. The meta game of Super Street Fighter 4 has numerous strong characters with favorable matchups. The meta game involves taking the matchup into account when selecting fighters, i.e. if a player is known to have a preference for a fighter like Ryu then his opponent can play the meta game by choosing Balrog (American version, aka "Boxer") as a hard counter because the matchup generally favors Balrog.
