If you don't know about it there are a few select top players that organize a player hosted tournament called NAO. Pretty well done and some great games.
You can look into it more at arena junkies or watch their stream at twitchtv.tv/naoinv

They have about 4k in prizes and are giving away and entire gaming computer for the tournament. link below for those interested.
