Ok,
First off, no way to incorporate 8 players, unless you take away from how the game was set up to work (6 player games)
Secondly, Katya has a very good solution, but I don't believe that this tournament will deal with semi- finals, since it was not discussed at the beginning of the tournament.
Iron Man Series 4- maybe
Thirdly, I am checking into the games right now to see which map none of the 3 players have won.
When I have finished that, I'll randomly pick one, and that is the one they will play on
Same settings, same everything.
Finals start when we find our 6th place.
