So, looks like we're down to Argentina, Brazil, Germany, and Indochina. Here's how I'm going to run the final round. I'm going to use my random number generator to randomize the matchup, and pair two sets of two teams against each other. The victors of those two games advance to play each other for first place; the loser takes second place. The losers of those two games play each other for third place.
*Randomizes the matches.*
And the dicebot has decreed that:
ARGENTINA v. GERMANY
and...
BRAZIL v. INDOCHINA
