Please make something like Steem Gallaga or Steem Defender :D
Many of us remember how exciting it was seeing "Steem Retro" offer the first Steem game you could earn steem from playing, and it was Steem Pac Man and it ended after only being available for a few months...
That will be up to the game dev community to do it! Initially we will be concentrating on providing the platform that game dev can provide their games. But, we will be making tools to make it easier to have the game economic system tied onto STEEM. And if at the end, no one is making a Steem Defender, may be we will consider it :)
