Good in principle, bad in practice. This would be difficult to implement and probably wouldn't increase the player base enough for it to be worth while. A month (or even a few weeks) is a long time to wait for a prize in the world of video games. I also think this system could function in a way that is unfair, for example: if this was around when Hornemans had his town, chances are he would be getting a lot of prizes because they would all reference his name because of the town.
