Hell Creek

67 million years ago in what is now Montana the dakotas and Wyoming there was a wellspring of dinosaurs and prehistoric animals big and small living among each other in this large ecosystem. The environment is hospitable being a mixture of a forest and swamp with many crocodilians and dinosaurs to worry about with the humid air it would be impossible to even breathe there as a regular human. You are a dinosaur living here you will first start off as an egg raised and depending on your species you will survive this hospitable land. Also to make this more realistic the AI is told not to speak so there is no talking to deliver maximum realism but if you do want to speak with your species there is another talkie that is available.
