Within my game there are regions/caves which you can purchase with coins. Coins are obtainable by mining obstacles specific to the region/caves. In addition to obtaining coins, you can obtain materials which can be used to craft new weapons in combination with coins.
How can I properly balance the amount of coins gained from obstacles, the damage from weapons, the required materials for crafting new weapons, and the cost of new regions to make sure players don’t get bored of repetitive gameplay?
Sorry if that made no sense.
