We have to buy the quest machine out of our own hard earned credits. (cost is 30,000)
We have to supply the prizes (or be lucky enought to have friends help with this)
We have to create the idea and the quest ourselves.
Now, I think it is fun creating the quest and do enjoy running it. However, the cost and the prizes could really drain you quickly. You get nothing from it except the self satisfaction of adding something fun to vmk. That's what it is to me.
