People don't get paid for the same work equally over the world. So the cost for the total chain is more expensive also. And the chain is long; The bare DVD box, printing the inlays, pressing the CDs, printing the manuals, assembling everything, packaging, shipping to the distribiturs, distributing the game to the shops, putting the game on a shelf.
There are a lot of people in this chain and all want to be paid. Countries don't have equal wages and don't have equal taxes. So who knows if they earn more money with Riftrunner in the UK compared to other countries.
