Kotaku asked the question on Microsoft GoD pricing...
Microsoft's Games on Demand pricing isn't exactly consistent across this orbiting ball of dirt we all call home. What costs $20 in one place costs $40 (or sometimes more) in another. So we asked Microsoft, why the discrepancy?
Microsoft HQ said the pricing decisions outside the US were the responsibility of that particular territory. So, for example, if Mass Effect is priced at 6000 Microsoft Points in Australia (as opposed to only 1600 MSP in the US), then that's Xbox Australia's decision. That's fine. So we asked Xbox Australia. Their response?
No one retailer has the lowest pricing for every product, and our program is about giving people 24 x 7 convenience and selection when shopping for Xbox 360 games.
We're incredibly excited about what Games on Demand means for digital distribution, and will continue to evaluate and evolve the service to meet market and consumer demands.
