I've seen games do that, mostly Gameloft's, but it's not perfect (the message was shown to me when I restored my backup with a legitimate copy to another, new device, and wouldn't let me play it. Needless to say, I was annoyed).
- Turing_Machine 14y agoI'm guessing they're using the device's UDID (or some roll-your-own analogue). One solution might be to let the user tie their copy to an external authentication service (Facebook, Google, some other OpenID provider). If you wanted to minimize user hassle, you could only require this step if the user wants to move the game to another device (and of course you could limit the number of devices allowed at any one time, similar to Apple's authorize/deauthorize for devices). An inconvenience, sure, but not as annoying as not being able to move the app at all. Note that I'm not saying that this is THE solution, just the one that comes to mind immediately. Does anyone see a problem with it?
