What is Amazon GameCircle?
Amazon GameCircle gives you more ways to enjoy your games on Kindle Fire. With achievements, you can track your progress as you play. Leaderboards let you compare your scores. For titles that have enabled Whispersync for Games, your saved data is stored safely in the Amazon cloud so you never have to start over again.
And most importantly, Amazon has built a Unity plugin for us developers to integrate this service easily! (Unity plugin link)
GameCircle API: https://developer.amazon.com/sdk/gamecircle.html
This month, we are glad to invite three members from the Amazon GameCircle team to come and tell us more about Amazon GameCircle and how to integrate it with our next Unity 3D Kindle titles!
Achievements, leaderboards, social, high-scores, cloud saves, and more! I think that's quite enough convincing. You know you need to come to this one. ;)
