30We don’t mean to blow anyone’s minds, but there are a few different languages spoken in the EU. At least three. This poses a unique challenge for developers dealing with cross-world functionality, something that has been relevant with the Guild Wars 2 WvW system; linked worlds have generally stuck with the same language for the playerbase, so that everyone can communicate freely.
