I'm unaware of any apps that behave totally differently in different regions. Sure - there are sometimes a few disabled features in one region or another, but is that really worth shipping a totally different binary for? Even language packs can be tiny even for 200+ languages if they're pure text. It's only when you get language/region specific artwork that there's a problem.
