Hey IMC suppose the iCBT(international close beta test) has a limit on the number of player that can join.
As it stands in google trends. The top 3 countries talking about Tree of Savior is 1st Philippines, 2nd Thailand, and 3rd Brazil. The iCBT application will be filled up by players from these regions.
There should be a wide sample from many different countries that are interested in the game.
