"USD only for App developers, WWW for buyers"
I translate it to myself:
"west: place with creative smart people. rest: dumb idiot consumers"
This is what always happen with 'gaming marketplaces', and 'mobile marketplaces'. This is the case with XNA, X-Box Live, android market etc... As someone from Hungary (Eastern Europe) I was naive enough to get excited about some of these in the past. I no longer do that. My first task is to check for this 'west-rest' rule. If I smell this I avoid the stuff like plague.
Maybe a good startup idea for someone who is reading this: create non-protectionist gaming marketplaces? I think there would be huge demand for that.
