My wife and I are about to get a second iPad so we each have our own. Up to now, we've had all our iOS devices (her phone, my phone, and the family iPad) all one one AppleID, which is handy because it allows us to have the apps we want on each device with just one purchase. However, going forward we're going to want to do multiplayer gaming, and particularly asynchronous multiplayer gaming, using our iPads. (Up to now the only multiplayer iOS gaming we've done is pass-and-play stuff, because we mostly game on the iPad and only have one anyway.) So my question is twofold: 1) Is there any way to set up multiplayer games using a single AppleID? In other words, can I start a game of Uniwar with me as player 1 on my device, and her as player 2 on her device, but all on my AppleID? I assume the answer to this question is "No, don't be stupid." 2) Is there any way for us to share apps without buying them twice? Most of my apps are just for me, but we have lots of games that both of us use, and a fair number of apps we bought for our toddler that it would be good to have on both devices. If the copy of Uniwar on her device is "owned" by my apple ID, could she still play a multiplayer game under a different ID? That's really the key question: can I have her iPad have "my" apps on it while still letting her log into them as herself?
