The toolkit, which offers a raft of services to devs, and to players functions as a game network similar to Xbox Live or Apple’s Game Center, can be implemented in iOS, PC, and Android titles. More info is available at Google’s developer portal, here.
Google Play Games’ Greg Hartrell said earlier this year about the company’s aspirations for the service and tools.
“Our game services are there, and our game network is there, to bring together this concentrated network of people who love playing games — to make it easier for someone who is a game creator to reach that highly valuable audience,”
The Google Play Games service is designed to help developers create mobile games for both Android and iOS devices, as well as browser games.
