THIS IS NOT ENTIRELY RANDOM!
These are the people who make it into the first round with no games:
3D House of Beef, Narusa, ArturusX, Belthazar666, A user name, Dm1321, Appawesome, and BurnOne.
They all start with a number/capital letter. Rastafla, Wanderer88, Ninthlite, Troh, VeryBored, and Mntoothpick did not get a free pass because the first 8 in alphabetical order made it in round 1 without going against anyone.
The numbers asigned are in alphabetical order, too. 3D House of Beef, has 1 because number come first. A user name has a 2 because his name starts with a capitalised A... People who start without a capital letter get put behind people with capital letters.
In the Preliminary brackets, if you add the two numbers together it is 33. The bracket with bamboe and brion have 16 and 17. 16+17= 33. The bracket with Mntoothpick and ytn2006 have 9 and 24. 9+24=33. (Yes, it works with all brackets in this preliminary.
Maybe these are just coincidences.
