I don't think it's out of line, I mean it does mean 'Game' in French.
according to Wikipedia there are 350 million french speakers in the world, and less than 100 million in France alone, so I wouldn't look at this sale in terms of just one country.
'expensive' is a relative term, if a French media company bought it, the price to them probably wasn't expensive. If the average person bought it for investment, then maybe it would be expensive to them.
look at what ireport.com sold for, if someone wants a name bad enough they might be willing to even overpay.
