GOG.com has confirmed that the three titles attributed to its recent announcement of the introduction of regionalised pricing are Age of Wonders 3, Divine Divinity: Original Sin and The Witcher 3 Wild Hunt.

The distribution of all three games on GOG will not include copy protection, adhering to the platform's long standing crusage against Digital Rights Management (DRM), however in order to attract new release products from larger publishers, GOG has had to compromise its single worldwide price commitment.

An extensive blog post from Guillaume Rambourg explains the reasoning behind the decision in great detail. Here's is an excerpt that best summarises the new stance:

We need to charge the recommended retail price for the boxed copies of the games in order for developers (or publishers) to either not get sued or at least get their games visible on shelves. You may recall that our sister company CD Projekt RED got sued for that in the past and we don’t want our partners to suffer from that too.

On top of that, you have to know that there are still many top-tier devs and publishers that are scared about DRM-free gaming. They're half-convinced it will make piracy worse, and flat pricing means that we're also asking them to earn less, too. Earn less, you say? Why is that? Well, when we sell a game in the EU or UK, VAT gets deducted from the price before anyone receives any profit. That means we're asking our partners to try out DRM-free gaming and at the same time also earn 19% - 25% less from us. Other stores, such as Steam, price their games regionally and have pricing that's more equitable to developers and publishers. So flat pricing + DRM-Free is something many devs and publishers simply refuse. Can you blame them? The best argument we can make to convince a publisher or developer to try DRM-Free gaming is that it earns money. Telling them to sacrifice income while they try selling a game with no copy protection is not a way to make that argument.

Age of Wonders 3 has now been made available for pre-order on GOG for "$39.99 or the USD equivalent of £29.99, or €39.99", the same currently offered on Steam, sans DRM. At the time of this post, pricing for Australian vistors was showing the US$39.99 figure, so it appears we've been spared a markup on this one for the time being.

Rambourg's blog post elaborates on plans for regional pricing of the platform's many classic games:

For $5.99 classics, we would like to make the games 3.49 GBP, 4.49 EUR, 199 RUB, and $6.49 AUD. For $9.99 classics, our targets are 5.99 GBP, 7.49 EUR, 349 RUB, and $10.99 AUD. This is what we’ve got in mind at the moment. We’ll do our best to make that happen, and we think it will.

The comments indicate that GOG only has fixed price differences in mind, unlike The Humble Store's recent announcement of a floating exchange rate that is updated daily.
