Yep. So this buyer is going to need to buy all his/her games from the US as well.
Plus, they're probably going to need some convertor to convert to the electricity in India, which I assume is different than here.
As far as customs fees, they'll probably have to pay some. It really depends on the country into which the item is being imported. I'm not sure what the fees are there, but the fees I know the fees can be fairly steep to Canada (I once shipped an item valued at $40 and they got something like $9 in fees).
