The answer is, Yes, you can do that. You can use Game Center to connect users using Apple's matchmaking services. This allows you to send push notifications to other Game Center users to invite them to connect.
There's also the underlying GameKit framework (which Game Center uses) that allows you to create an ad-hoc network between devices in proximity over BlueTooth or Wifi. You can also dive into a bit of hardcore C and use Bonjour to connect devices. I use both peer-to-peer and Game Center connectivity in my game Cee-lo .
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
