Why are you not buying this on Steam right now?  It's incredible!  Why are you still reading this?  GO!!

The Stomping Lands

UPDATE:  I totally got suckered into buying this.  The devs took the money and ran.  Way to go guys.  Hope it was enough to keep you going cause you aren't welcome back to doing game development.

This certainly looks interesting.  The Stomping Lands. It kind of seems like a cross between Carnivores, Rust, and little bit of Turok.  So you try to hunt and survive in a dino / tribal world.  Apparently it has gotten Steam greenlight but I can only find it on the Steam web site, not the app.  Definitely something I'm going to keep my eye on.
