Yes, If you add the Update kit to your pledge you will receive the rulebook, production tiles. commander cards, and all of the components with text you will need will be translated. We have the language packs for French, Spanish, German, Italian, Dutch and Polish. In your core game you will still receive also the English game components and rule-books.
This will all be handled in the Gamefound pledge manager. Kickstarter does not allow for this type of functionality easily so after the Kickstarter ends you will have an account with your details, pledges, credits etc... imported into Gamefound. Developed by Awaken Realms this 3rd Party Pledge Manager system has worked extremely well for us in the past.
