iOS 4.1 added Game Center, which supports the concept of achievements. These are game-specific accomplishments or events. Right now I’ve got about 40 different ones planned, though that may change. They include obvious things such as winning the game, winning as Queen of Dragon Pass, or winning as a Peace Clan. Spectacular ways to lose are also achievements, such as the Beastfolk Apocalypse.
Note that Game Center supports hiding of achievements — until the Beastfolk trash your clan, this doesn’t appear in the list. This helps prevent spoiling certain story lines.
I’ve entered 11 via Apple’s web site, though not all are hooked up yet. Here’s what it currently looks like in the Game Center app.
Let us know if there’s something you think should be an achievement.
