really cool find, that is some interesting stuff. The whole idea of challenges and gifts seems very strange to me. But then again achievements seemed strange the first time I heard about them too.
I wonder if challenges and gifts are completely user generated? it seems like devs need to program this ability in and the entire subjectivity of a challenge issued from one player to another will be lost... but maybe there will be a controlled way to select a preset challenge from a list.
got me interested.
