See, this is the issue, 'cause we had a box (or was it two?) of space hulk sit in our store for literally years before getting sent back to the warehouse. Space Hulk sold extremely poorly in Australia, and IIRC, we normally snap up the boardgames pretty quickly.
On the opposite end of the spectrum, look at what kick-started sisters - cannonnes verydian sold out 3 times in a week and turned out to be sufficiently popular to change from limited release to store item (albeit webstore only). Again however, she sold really well here in Oz, but the extra stock they got after selling out the first 2 times came from other areas where people didn't buy it.
