Very little. A translated rulebook would be all you would need. The only other item in English are the building names.
We are not offering any retailer discounts above the shipping discount that would naturally happen when pledging for multiple copies.
The reason for this is the price of components for the deluxe edition is such that we can't really afford to charge less for the game.
You can! Just add the correct amount to your pledge total.
For example, if you wanted 2 deluxe editions and 1 standard edition you would pledge $160 dollars (60 + 60 + 40)!
