It is so exciting seeing not just a sketch of a totally different kind of game, but also a different way of thinking about games. Different concepts that come first, different structures, what was left partially defined or intentionally left undefined.
The lack of feedback and real collaboration is a fascinating experience, also. Like, with the possible exception of "subtweeting" here, or whatever, this is essentially a collaboration without collaboration. No way to know or guess at what someone hoped would happen to their thing.
I'm excited to see what transformative processes are revealed at the final stage!
