Could this be the first sighting of Google Play Games? A game by the name of Eufloria HD received an update, and its changelog makes mention of Google Play Games achievements. Google Games has been rumored for a while, with sightings in multiple places (like the Google Glass app). However, a game has now integrated it. Does it work as advertised? Is Google’s service already up? Will it be announced at today’s Google I/O? We don’t know, but we can’t wait to see! For now, you can give this game a download (there is a free demo) and see for yourself.
