I would describe “social game-play” as two or more players working together to accomplish a singular goal.

A good example of what I’m talking about may be found in the Facebook version of the popular game, Civilization; due out in 2010.

I’ve been looking at ways of expanding the [Civilization] gameplay experience to include solo, competitive and cooperative play to take advantage of the uniqueness of social networks. (From Mashable.com)

From my experience with the game Spymaster, it’s hard to tell whether or not the behavior of creating social game-play has involved a majority or minority of players.

The site SpymasterFans.com was created within a few weeks of the game’s launch to help players connect and create cells. Now that the game has built-in cell tools, many of the cells that once existed on SpymasterFans.com have left. Right now the site has more than 1000 members and close to 50 cells, but the major cells aren’t listed.

The largest cell, Zone, has its own website, spymasterzombie.com. Another large cell, Puma, uses Tinychat.com to communicate. There are other cells cites as well, like http://phnx.realbb.net/ or http://www.thunder-struck.nl/

I don’t know how many people are actively playing Spymaster, so it’s hard to gauge whether this is a majority activity, but it doesn’t appear to me to be an anomaly.
