Purchasing from Getchu gives you a 'characater profile card' of a character whom I can not remember
Purchasing from sofmap.com gives you profile cards of Rance and Sill
and Purchasing from the Alicesoft store gives you::
"First year of Heisei specifications grated draw
replacement package jacket"And I have no idea what that means!
They're also selling a Rance01 calling card on the Alicesoft store; there's a chance that it will be included with the boxed edition (as was the case with Sengoku through to Magnum) but I bought it anyway because I was momentarily shortsighted by my excitement.
