There is some language dependency:
+ The game has reference material on the player screens and on the note sheet. Once you know the rules of the game and of the logic puzzle, that shouldn't be a problem.
+ The app has icons, so most of the app is language independent.
+ The big areas for language dependency are the research action and the Planet X conferences. These will present logic rules like, "Every comet is within 3 sectors of a gas cloud," and for that you will need to be able to read the results.
We plan to support English, French, and German in the app when we launch, and we'd love to work with partners to translate the app into other languages.
