Once the Steem sign-up process is fixed with the next hardfork as well as having the SMTs online...why not approach agar.io with that proof of concept and telling them that they could integrate to Steem?

What this means is that players can get paid with steem token other than the upvotes they get when they comment.

I think it's a nice idea ,if that's what it means because more players will join and it will be a huge way to promote and bring more people into the steem blockchain especially those who like gaming.
