Just a thought, but can we have i18n files so that players can create their own translations for the game?
Something like:
{gameFilesPath}/translations/en_US.xml
{gameFilesPath}/translations/de_DE.xml
{gameFilesPath}/translations/ja_JP.xml
And them we can select in the options menu which language we want to use.
This way, the developer doesn't need to spend time creating translation for some obscure languages and the game can be accessible to more people if there are translations already created by others.
