While the three dimensional objects look a little blocky, you'd be surprised at how much expression this team has been able to convey with the turn of a head or the raising of an eyebrow. It's worth getting to know the folks you run across. You do get the feeling that everyone in this game has a rich and full background, regardless of whether they want to share it with you. Half the fun is talking to folks, piecing the clues together . Don't take it personally, just remember that some of the aggressive ones have cash and other goodies in their pockets that can be confiscated for your benefit.

But some folks . Those who do have a skill or two that you will learn to rely on. As long as you keep smiling and talking . . . or not even smiling, really . . . It's just a little reward for being neighborly. But frankly, talking to people can only hold your attention for so long before you want to go kill someone.
