On a rugby field, each side has the same number of players (regardless of how important the country). Each side gets to choose its own captain (the other team doesn't get a say) & teams change ends at half time to give each team fair use of the prevailing conditions.
On a rugby field, referees and linesmen are strictly neutral and take swift action to ensure that the rules of the game are observed (e.g. penalizing players who are off-side); minor misdemeanours are penalized & deliberate acts of violence result in the sending off and possibly suspension of the guilty party.
On a rugby field last week, Georgia beat Russia 38 - 8 to win the European Nations' Cup.
