I am seeking clarification on part of the guidelines for In-App purchases.
Any credits or in-game currencies purchased via in-app purchase may not expire, and you should make sure you have a restore mechanism for any restorable in-app purchases.
Let's say I have characters in my game that to advance you have to use a couple different resource types as well as a gold type currency. Those different resource types, can they be considered currency?
Two options for the user to purchase these reources:
Option A, the user buys those resources using in game credits. These credits can be earned in game or purchased with actual money through In-App purchases. Since real money isn't used, can those resources be allowed to expire?
Option B, the user can purchase those resources through an In-App real money purchase, are they allowed to expire?
