Thanks to all three of you for responding. Perhaps I am downplaying the role for regional pricing and yes I live in the US and my point-of-view is skewed. Let me ask you this. Were you planning on purchasing any of these games before they became Epic-Store-exclusive?
With that said, there have been at least three similarly themed threads with numerous indignant posts about how unbelievably awful this is. Other than regional pricing (which is clearly of some importance to some) and which Epic can hopefully address rather quickly if they wanted to, I still don't see any compelling reasoning for why this is so bad. Muad'dib, I saw your additional reasoning and I agree that on principle, one could be upset about the walled-garden approach. I would counter that given your PC can play the game regardless of storefront, the "wall" doesn't really affect you. If it's principle that's keeping you from playing, then so be it, but it's not the "wall".
As a matter of fact, I was going to buy Ashen on Steam. Annapurna has a pretty good track record for regional pricing so I "knew" that I would be able to afford it. I would have bought Supergiant's game as well, since I loved their earlier releases (though that one didn't exist in my mind before today, since it was just announced at TGA).
And regarding Epic's ideas about regional pricing, I asked Galyonkin on Twitter about it, and he basically said "in the future" they'd add more currencies (a very nebulous future). He also claimed that there's support for regional adjustments of prices right now, when friends who live in countries that are "supported" told me otherwise.
So in my situation (and the situation of many other PC gamers, I'm sure) it's not a "fake wall" that's preventing me from playing those games. It's a very real wall made of dollars I don't have.
And once again, thanks for downplaying the role of regional pricing when you clearly don't know anything about it. It's not the first time I'd seen this kind of thing, but you were very open about your lack of caring about regions that are not the US.
