I would like to suggest a "Monthly Headgear Box" that only obtainable by spending (read: gambling) MCs.
The objectives is to create balance between hard core grinders and donators, so that the economy will be running smoothly. There will be people EARNING money, and there will be people SPENDING money.
Let's say the box is costing you about 20MCs per box. Depending on your RNGesus luck, you might get one of this : common, rare, super rare, or extremely rare HGs.... if you get the common, you will lose your gambling money. If you get the extremely rare one, you will make more money.
Basically the RNGesus thing is the only ONE FACTOR that affects your investment (the gambling money xD). No skills required, pure luck system implied.
These are my rough ideas about the RNGesus chances :
1. 50% Common HGs - sellable for not more than <10b
2. 40% Rare HGs - sellable for 10-45b
3. 7% Super Rare HGs - sellable for 45-60b
4. 1% Extremely Rare HGs - sellable for >60b or more
THE LEAD GENERATING TOOLS
(or you can call it as an ADVERTISEMENT)
We can change the whole gambling outcome every month. So every month, there will be an update news in AnomalyRO patcher saying "this is what you can get from July Monthly Box blah blah blah, click here for more information" and when players click on that link, they will read the information on forum. Perhaps including the pictures as well. This will create the demand for the marketplace.
And also, changing the box outcome on monthly basis will motivate people to farm for MCs immediately if they want something in one particular month, because they know they are not going to get it if they wait for the next month (to create the sense of urgency)....
I see this as an opportunity to make GR running all the time.
The donation-oriented players will help the server to financially sustain.
The hard-core grinders will help the server alive.
And I think that's balance.
