With what I have said above, it should just about explain what to expect here about graphics. You would expect to be able to pump the graphics fairly high given the fact that it is an outdated engine, but it really didn't like doing that. They spent some time and some work on the characters, and that's good, but you are going to see the same ones over and over and over and over again. There are so few characters in the game that they were able to sit and list each one of them individually in their game manual.
Don't spend a long time waiting for a deep and immersive soundtrack or voice over, because it ain't coming. If you speak Russian, you get a short blurb at the beginning, but alas I had to start out in the dark just like everyone else. Instead of voice, you will occasionally get to read a note to get through the game.
