This is a wonderful game, I absolutely love it and the idea behind it. Its so much fun to spawn in a massive amount of herbivores and then a couple carnivores and watch the herbivores swiftly die out as the carnivores multiply. But through doing this Ive noticed that there are some things that should be changed. The crocodiles dont ever die, and I havent yet seen an herbivore kill one yet. Same thing with the birds, they fly around and destroy all the trees, but nothing can keep their populations in check. I think carnivores should definitely be less aggressive, but they should also try to hunt down other carnivores, as well as a carnivorous bird that will eat the other birds and can be eaten by ground carnivores. And as mentioned by others, I think the idea of "people" would be great! So long as it doesnt turn into a spore/sims mashup :P
