Basically all SUB games that have micro transactions are for items that have no in game effect other than looks or so little an effect that they are not 'Pay to win' items. It's the FTP games that most often have pay to win options to ensure players actually spend money. As for Nutaku.... i'm kinda glad and kinda say that they have not fixed their gold buying system. I cannot buy nutaku gold from australia since they have still not fixed the Paypal option and thus cannot even enter these sort of things.
