I was watching old developer commentary on game design and Rob Pardo brought up the aspect of a community experience of unlocking expansion content as a server-wide effort.
I began thinking about how crazy of an event that would be if it was done in today’s game environment. It’s such an interesting concept. (which was replaced by server-wide events instead of community efforts)
