Merch Store Events
Events so far have rewarded players with special currency to purchase character cosmetics. Imagine if future events provide a special currency that can be used for physical items from the new merch store!
This would be a single, persistent currency that is earnable in all events, along with whatever event currency is developed for cosmetics. There would be a limit that can be earned per event. Once you reach a certain amount (perhaps the max limit for 3 events) you can redeem by exchanging the currency for an coupon code sent to an email address you provide. I would say that each code would be worth $5.
This rewards fans for playtime with monetary discounts, but should be structured as a slow earn so that very few people will purchase items “for free” using the discount codes alone. This will also increase the stakes and participation of events significantly.
