This is a very interesting idea. Kind of like a game of life coin or something. Is it possible this could be implemented alongside HUC, or does it make more sense to launch a separate chain?
It was pretty easy to set up the skeleton of a game that will run on the Huntercoin blockchain alongside the normal game. It will look like this and I think will be playable at block 1400000.

While the creatures are named after hunters, these hunters can be long dead. (theoretically they could also be anons)
Things to choose when making a new critter: fireball range for the lemures but at exponentially increasing mana cost (they have a lifetime limit),
tendency of the zombies to teleport away (but this will also bring them away from the gems), and randomness of movement.
Basically the game is about guessing the population dynamics several hundred blocks in the future.
Once sent into battle there will be no way to control the creatures and they'll live out their lives (on the blockchain)
Compared to "Allow Standard Names in Huntercoin" (

this is the pirate version. Doable right now and, of course, no 1000 Huc fee per name
