I think it's great if there's a game like mmorpg that base in steem/cryptocurrency, since I'm also a gamer, I think this is a big opportunity to enjoy also to earn.
And since some players do marketing style game play specially in MMORPG world then their game item and asset will be worth something in real world, and not just by 1010110 currency that some point in time become worth nothing.
So, gaming currency like gold is best to be remove and change to cryptocurrency such steem that their account is direct link to their digital currency wallet, so hyper inflation that mostly happen in game economy.
