This is with regards to Wasteland Remastered which is currently more expensive in south america, at over 18 US dollars than in other wealthier parts of the world. The US price for example is 15 dollars. And the UK price is £10 (about 13 dollars). Less stable currencies of latin america can make this already more expensive price even more expensive after conversion.

Usually when these mismatched prices happens it's because the regional prices hasn't been set properly. This had happened with Destiny 2 expansions when it first launched on steam. But it was fixed within a few days. Hopefully GOG (and steam) can do likewise with this title!
