Here's a sticky thread to put achievement-based ideas and discussion.
Our plan is to engage game developers to send us periodic information about your game play, such as how many castles you've toppled in Crush the Castle, or how many times your dinosaur jumped in Treadmillasaurus Rex, etc. and that these pieces of information would accumulate to award you 'achievements' on AG3.
We're actively designing and building the achievement system right now, so as we have information, we'll share it here, but we're welcome to listen to ideas and feedback along the way.
