cogadh: Thread is TL;DR, so if this was mentioned before, sorry. Is it possible that the reason the Kiwis are getting screwed is simply technological, like the IP ranges used by Australia and NZ overlap each other in some way, preventing GOG from distinguishing them properly?
That's an intersting point. If that were the case though, the correct thing to do would be to go "Oh well, we can't stop Australians downloading it*." rather than "Oh well, we'll have to stop New Zealanders downloading it*."
*The uncensored version.
More likely it's a licensing issue. If Namco Bandai treats both countries as one region and only does one version for the two of them, it's likely they're forcing GOG to give NZ the censored version for the same reason they forced them to do it for Australia.
Namely, GOG is competition for Namdai and don't want them to have an unfair advantage.
