One could also think of the idea, that the statue issues by the owner selfmade coins. For example one per user and day. These coins can be taken by players by just watching the statue. All they need is an app and a steemit account.
With these coins they can buy goods from the statueowner.
For example a bar-owner has this statue in his bar. He can give a drink for free if someone sends him one of his coins.
Or a shopowner can sell some products with a rabbat.
Only people, that goes to the location of the statues, can get these incentives.
