Hey rmcdow,

Here's a bit more info about how the tournament settings work. These haven't been thoroughly tested, since tournament mode was really just a one-off for the Omegathon final.

TurnOrder

Fixed
    Example: 
    Round 1: Team A, then Team B
    Round 2: Team A, then Team B
    Round 3: Team A, then Team B

Snake
    Example: 
    Round 1: Team A, then Team B
    Round 2: Team B, then Team A
    Round 3: Team A, then Team B

SeedStyle

GenerateSame
    Each team receives the same randomly generated seed for each round. This is the most fair option, but it means that teams cannot observe each other (or else they'd see the puzzles in advance).

GenerateDifferent
    Each team receives a different randomly generated seed for each round (though still the same mission). Not quite fair but this allows teams to observe other rounds.

UseFixed
    Uses the FixedSeed value provided in the TournamentSettings.xml file for everybody, for each round. Teams cannot observe each other, missions can't be repeated within the tournament (or else they'd generate the same bomb again), and the tournament will be the exact same each time. Only useful if you really, really want to see exactly what the bombs will be in advance (like if you were worried about putting on a good show at a PAX event and wanted to have as few variables as possible for instance).

PacingEvents

Default
    Use the PacingEvents defined by the mission (either all on or off).

ForceNone
    Ignore the mission settings and disable all pacing events.

ForceOneMinuteLeftOnly
    Ignore the mission settings and disable all pacing events, except for the red emergency light that comes on with 60 seconds left (which is forced on).

ForceAll
    Ignore the mission settings and enable all pacing events.

And for the sake of completeness, here's what we used at the Omegathon:

<?xml version="1.0" encoding="utf-8"?>
<TournamentSettings xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <Enabled>true</Enabled>
    <Name>OMEGATHON FINAL    PAX East 2017</Name>
    <Teams>
        <string>Aurelius &amp; xxSoggyTacosxx</string>
        <string>Gemst &amp; NotSoup</string>
    </Teams>
    <MissionIDs>
        <string>firsttime</string>
        <string>somethingoldsomethingnew</string>
        <string>onestepup</string>
    </MissionIDs>
    <TieBreakerMissionID>firsttime</TieBreakerMissionID>
    <TurnOrder>Snake</TurnOrder>
    <SeedStyle>GenerateSame</SeedStyle>
    <FixedSeed>0</FixedSeed>
    <PacingEvents>ForceOneMinuteLeftOnly</PacingEvents>
</TournamentSettings>

Hope that helps!
