There are a number of graphics for carnivore resources, but how would we use them in game? They would not work well as resources but may work as improvements or features which we implement as lairs I suppose.
*rubs chin* I was more thinking of the Romans and Persians. They used Lions in the Colosseum as well as many other cultures based their ancient myths around various large cats.
If we are moving to put more 'mythical' stuff in the game, I was thinking of Lion Riders XD (I mean, I would rather ride a lion then a Deer into battle.)
*shrug* I was just trying to figure out a way that resources could still evolve through the future ages. Lions are a protected species in most countries (or at least rare) so a spot of land with them on it would most likely be 'protected' and not able to be turned into farmlands and what not. These 'Lair' tiles might need special improvements and buildings to advance them.
Then just creating a Lion Cage wouldn't give you lions, you'd need to find a lair, put the improvement on it, then build a Lion Tamer, (which gives +1 happiness with Colosseum), ect, ect.
I am really just brainstorming here, but I think if you guys broke the resources down into structured categories, it might be easier to plan upgrades. For example:
Mount Creatures:
Elephants, Horses, Mules (Donkey?), Zebra, Deer, Ox (Buffalo?), Mammoth, (Unicorn, Pegasus, Dire Lions, ect).
It could be easier to see what still needs what. Each one could have it's specific stable, you could even go so far as needing to 'domesticate' them rather then just put the herd in a city.
It really all depends on how much detail you want to go into and if you are going to include mythical creatures or let someone else worry about them?
P.S. I am not sure if you can create a unique category for creatures in game, like resources, but if you could it might be easier to apply specific bonuses from specific types of creatures to buildings easier.
- For example, having a Domesticated Ox herd could give a +1 somewhere because now people don't have to do things by hand, they can use the ox. And, if you have it as a category, now all the buildings that need a 'labor or mount' type creature in the city gets a bonus. No more plowing by hand, no more pushing carts around, you have your domesticated pack animals to do it.
