Brazil, a strong developing economy, is the largest country is South America, and has the biggest population of South America as well. From a game developer’s standpoint, it’s unfortunately also one of the ‘restricted’ countries. In short, this means you cannot submit a game – any game - to the Brazilian Windows Phone store without it being rated first. Since most developers outside of Brazil think this is a complicated and expensive procedure, and don’t speak Portuguese anyway – they tend to uncheck the Brazilian store and thereby leaving the Brazilians stranded, and denying themselves the opportunity to branch out in South America.
