It seems some players in countries like Australia, New Zealand, Brazil, and South East Asia are experiencing issues accessing the store page on Steam; for players trying to download the Gameforge client, the inability to download it.
Players from those countries who already have the game installed can still login and play though. To date, Gameforge has not yet addressed the question as to which countries they will be specifically servicing (besides a generic North American and Europe).
SoulWorker currently has publishers in Korea, Japan, and Taiwan. Apparently, there will also be a publisher servicing South East Asia in the near future. If that is the case, it makes logical sense for a region block out of respect for that regional publisher (or it may be specified in their publishing agreement). The block on Brazil makes no sense whatsoever though except as a temporary measure to limit new players from that country adding load over this weekend. Gameforge needs to make it clear what countries they will be servicing.
