It's a scenario editor that let's players create their own instances and DM them.
It seems quite nice and I'm dowloading it to test it.
You'll find info about it here:

I was wondering how they will avoid ruining their economy and avoid xp farmers until I found this post:
> Do players get exp for fighting mobs in the scenarios?
You don't get XP from mobs in a Ring adventure. We disabled the option to avoid getting easy XP and having scenarios of monster bashing. However we will reward players editing and playing adventures with consumables such as XP crystals (consumables that double the XP you gain).
> What stops players from making quests easy so they can get the treasures easy?
Regarding "treasures", for now the only ones you receive are mission items that the author will have created for his scenario. You don't keep them after a Ring adventure, there is no point.
We have some plans in mind to give the author the ability to put his own items from the mainland as rewards.
> If a player comes up with a really good senerio or design will it be added to the game?
Yes, we plan to "add" really good scenarios. in fact, from the way it works I could maybe say "distribute". A good scenario would be added to our list of scenarios available for all: any player would have access to it from his computer and could "activate" it on the terminal so that anyone could go into it and play.
