This looks interesting …
Really does. Hopefully soon will have assets for this!
Yes, I was reading about this; Google Play may become a little bit interesting now.
Damn really need to invest the Android license =__=…
Yeah, i got pretty excited when i read it on androidpolice.
Didn’t see anywhere a launch date…
It looks like it is already live with several games supporting right now.
I thought I would also provide a link to Google’s Android Developer guide for Play Games, so you could learn a little more about its features and how it is implemented.

Already got mine ready 
Has anyone messed around with android studio yet? I checked it out and has a lot of potential.
Wow. The Play Game Service Guide includes a section for using the SDK for your IOS apps. You can do leaderboards, achievements, and (most important) cloud save with both your Android and IOS version of the game using Google’s SDK.
Here is the link to the IOS section of the guide:
https://developers.google.com/games/services/ios/quickstart
I’m sure a lot of people will still want to use Game Center on IOS for leaderboards and achievements, but it would be cool to implement just cloud save to have customers being able to continue your game on different IOS and Android devices.
No they won’t. GameCenter has not been nearly as popular or widely supported as Apple probably hoped. Apple just hasn’t been nearly as supportive of games in general as they should have. Providing a cross-platform compatible solution is extremely canny of Google. This is going to go a long way toward bolstering development support for their game services.
We need someone to come up with a guide or tutorial for implementing this into Unity!
I have to agree. Where possible I’ll always opt for a cross-platform solution. Or, more specifically, I’ll always go to where my users are.
This time I went for Facebook and built the rest of the functionality into my own game/server. But if Google already has something that’ll do it for me on multiple platforms I’ll definitely let them take that burden off my shoulders.
- No multiplayer support for iOS
- Android SDK requires Google Play Account (i.e. Developer Console setup)
NEXT!
Is anyone already making a plugin for this?
Edit:
Seems prime31 already made it for iOS so for android probably isn’t far away.
Well I don’t think having an Android Developer Account is a deal breaker. I mean most mobile developers would already have that. I also don’t feel like iOS Multiplayer is a deal breaker either. This is probably good for the Android versions, and one can use GameCenter for the iOS versions.
We just created the plugin for iOS and is available on github. It is called UnityGPGPlugin
We are not sure where we can announce so that more people can have a look at plugin

Blog post for plugin http://www.nerdiacs.com/2013/05/17/google-play-game-services-for-unity/
Will add Android support in coming weeks.
Old post, but worth the try 
I finished a plugin that brings the Google Play Game Services API to Unity projects. It currently supports iOS, android and WebPlayer projects and the following features:
- Sign in with G+
- Display leaderboards and submit scores
- Reveal and complete achievements
- Real-time multiplayer (android only)
- Anti piracy feature (android only)
You can find more information here, and purchase it from here.
