Untitled - PlayFab

• Idle game created in Unity
• Initially designed for WebGL
(Kongregate and other web portals)
• Added full Steam integration (achievements, badges, IAP, etc)
and released on Windows, Mac and Linux
• 2M+ plays on Kongregate, and more than 130,000 installs on
Steam Early Access
• We discovered Playfab at GDC
• Installed SDK on my laptop on the GDC floor, and haven’t
looked back

• Don’t use device ID on WebGL! Every device ID is the same!
• Generate a unique auth token (most service providers already
have this)
• For example, we use Kongregate’s GameAuthToken, which is
unique to the logged in user
• Include support in-game
• Playfab IDs are difficult to type, and are prone to error
• Validate user input to ensure they provide all necessary details
(e-mail, refund request, baked in Playfab ID, etc)
• Cache things that don’t change!
• We hit Playfab for saved game content once, and then keep
that data
• Playfab does *almost* everything
• However, when performing purchases in Steam you still must
register a Steam callback for a transaction

purchases

community, goodies, social networking.
• Does not maintain conservation of energy – the energy you put
in is amplified by the users!
• Prepare for customer support
• Ask questions! (Brendan and team are a great asset and help)
