I wrote the same to another thread, but what the heck...
truhlik: This makes me sad, reading all about regional locking :(
Not cool gOg, not cool.
What are the realistic alternatives for GOG?
This is not a restriction imposed by the game publisher with which GOG negotiates directly (well, maybe the publisher has told GOG not to sell the game in Australia, but I'm sure the publisher would want to do that, if they were allowed). It is the government. It is not reasonable to expect e.g. GOG to negotiate with Australian government to change their policies. What possible reason would Australian government have to agree with GOG, or the game publisher? I think they have zero incentive.
It is interesting question though what could happen at worst if GOG decided to sell the game anyway to Australians? Does Australia use IP filtering, like many other countries nowadays do (Finland included, e.g. PBay has been inaccessible from here for a long time, without workarounds)? So could it be that if GOG sells to Australians games banned in Australia, the whole GOG site would be blocked by the Australian filters, effectively banning all GOG games from Australians? Or some payment options between Australians and GOG.com would be blocked?
tl;dr: I think it is different when discussing about restrictions demanded by the game publisher, or some backwaters government like Saudi-Arabia, Iran or Australia.
Anyway, as I keep saying: vote with your wallet.
If you don't like the fact that the game is not sold to Australian IP addresses, don't buy the game. That'll show them!
(I don't know who is "them", but someone will really learn his lesson. Or her.)
