[QUOTE=tipztv] @thehen: Is there anyway to update the tile when the game is not running, using the plugin? Or I have to modify the exported project in VS to use that feature?[/QUOTE]
If you want to update a live tile while the app's not running, you either need to use local scheduled notifications, as documented here:
Or use push notifications, as documented here:
Given the feature list for the Windows Phone 8 plugin, you'll probably need to write some code in the exported project to support notifications when the app isn't running.
Windows Azure Mobile Services is a nice way to do push notifications, since it's cloud-based, and quite easy to use. And given that @thehen is working on a plugin for it, perhaps it'll be even easier once that's done.
