Oh great, finally something cool and interesting that's game related happens in my small country, and it's restricted to a place hundreds of kilometers from where I live, that's just great :|
Just confirmed on their Facebook page, that there are limited copies of Bloodborne and it will be determined on a dice roll. A six will secure a copy of the game.
A typical man is allowed to give more blood than a typical woman because they have a higher blood volume. So it is not the blood that is different, but the amount.
