How to sell multiple applications sharing vars in the App Store?

Question

I am struggling with a problem.

I want to sell one application in the AppStore. But I want to sell it in parts.

For example, you can buy one football team, and then buy each player separately. I was thinking of sharing vars between several applications, but I don't know if this is possible.

Can anyone help me? Where can I get information about this?

Thank!
