This developer demo is actually getting me excited
So big they've added mounts, from regular old horses to the more exotic.
I never felt the Dragon Age games looked too hot, but BioWare has done a nice job making a more lush world. And then you get attacked by a giant bear and freeze it mid-stride and, woah, that looks pretty cool.
There's also promised dynamic changes in the world. For instance, hunt too many of those bears for their skins and you may reduce their population. Reminds me of driving buffalo to extinction in Red Dead.
