To a game designer, everything is game design … including game design:

The most exclusive game on Facebook is also the most lucrative and intense: the game design of the games themselves. For designers in the space, particularly those from the traditional game industry, game design has become its own game, complete with a leaderboard.

“Every night at midnight, I check AppData,” says John Romero, a veteran video game designer, consultant and lead designer of Ravenwood Fair. The site has become a de facto leaderboard for many developers, backed up by weekly top games lists.

Imbued by a deep love of game play, many designers view social game design, and the competition it creates with other designers, as a real-time strategy game, complete with in-depth stats and armies composed of coders, artists, animators and product managers.
