Basically on steam it's the same like on humble bundle (or if happen on gog). The developer / publisher itself put's in the price for the different regions.
But one thing all tripple AAA publishers did was to make it "1$ = 1€ = £1". Cause yeah more money ... (shareholders and so on...)
There was (dunno if still is) an example of a well know publisher in germany which made germany pay €39.99 and all other regions cause not so well know 20$ ....
This just opens the chance of getting misused and it is very hard to find without setting up proxies and stuff.
I realy don't want to support it. I feel like facepunched ... first i'm asked to provide help and than using my help to force customer unfriendly solutions.
