From DnD to WoW

I am writing about the development of online gaming infrastructure. The idea is to pick out and describe the key services required for modern online gaming. I am putting extra words together describing how we got where we are today, this does two things, puts my understanding of this stuff onto paper and out of my brain and creates a chunk of knowledge to draw on when we begin writing about this in a more structured way.

Chatting between players is one of the earliest generic services for online games and has been present in every evolution of the technology.
