Honestly it's a primarily a monetary thing, and secondarily a logistical thing (since we're doing all our fulfillment in-house). In my mind, if someone outside the US wanted to buy the game and just added the international shipping to their pledge (and messaged us on KS to clarify that they're outside the US), we could probably fulfill it. But the question is: what is the shipping cost? Are there taxes etc? This stuff gets super expensive super fast. I took a brief look at DHL from Berkeley to Europe and the best quote I could find for a package that would contain 4 sets (our $110 tier) was $130. Admittedly researching optimal, affordable shipping isn't something in which I have a ton of experience. I am open to suggestions. But probably what would be best is if folks outside the country who are willing to pay a premium for the game could get in touch with me so we can figure out exact shipping costs, and then I'd ask them to pledge for reward + that shipping cost (at a minimum). I say probably because at this point I can't guarantee international fulfillment --but again, if there's enough demand, I'll see what I can do.
