sounds really interesting and we at @biddle are really looking forward for the go live of the SMTs.
We will definetly include this into the game mechanics, in order for SMTs to be found ingame, be rewarded with, being able to pay ingame or out of the game and so on and so forth.
This will give the first MMORPG on the Steem Blockchain a huge amount of new possibilities, that we will use to trigger off finally the thought of proof of game which will be a real blast!
