Well, that's the whole problem, isn't it... you are so convinced that you have a RIGHT to a lower price (because people in Russia get a lower price, and because you got a lower price for the previous game) that you simply cannot accept the fact that THIS game isn't available at a lower price yet (in your country). It may become available at a lower price at some stage (and it probably will), but it isn't right now. Does that give you the right to pirate the game and play it without paying (as you clearly suggested in your third post)? Definitely not! That is still theft.
Don't get me wrong, I know what people in Poland earn for a living, and how much of your income you would have to spend for one game at this price. I'm definitely not against Steam/GoG offering this game at a lower price in Poland (and I never ever claimed that the Russian regional price is fraud or theft!). I'm just saying that, as long as this particular game is NOT offered at that lower price in your country, then the only legal option you have, is to wait until the price is lowered. Anything else is, and always will be, piracy and theft.
A computer game, just like a Ferrari, is luxury goods. If you can't afford to pay the price that is (currently) asked for them, then skip them. Don't buy them, don't steal/pirate them, don't use them... just wait until the price is lowered to something that you are willing to pay for them. It's as simple as that.
And btw, GOG definitely DOES use regional pricing. Sure, you have to pay the full price (or what you call 'Western price' or 'EUR price converted to PLN') first, but then you get a regional price correction, and you get part of your payment refunded into your GOG account, for (in GOG's own words:) "ANY FUTURE PURCHASE. You get free Wallet funds (our Fair Price Package) to offset the regional pricing." I don't know how much the refund is for Poland, it still may not even be close to the price that you WANT to pay, but when you subtract that refund, the total that you actually have to pay for this game on GOG is definitely less than the 220 PLN that you mentioned.
