The living world, which now boasts 1000 unique characters to the last game's 400, doesn't just mean you can't buy stuff at night because the shopkeepers are asleep. It also means that your reputation will have meaningful implication in the game world. A.I. henchmen will hear about what you've done and might refuse to help you based on your past exploits. Some cities will be openly hostile. By way of example, Berger suggests a situation where you might need to get into an orc city, but if you've been helping the humans, the orcs might not be kindly disposed to you walking into their city. You can, of course, fight or sneak your way in. Or you could free enslaved humans to help you fight. Berger suggests a particularly novel approach as he shows off a T Rex, apparently unsure of its place in the food chain, calmly grazing in a field. He says you could lead a bunch of T Rexes into the city to scare the orcs. "They hate that. The orcs hate T. Rexes, so they'll run out of the city," Berger says.
