While the look isn't particularly impressive, I had a hard time getting the game to run decently. Turning all effects off and lowering all the graphics settings to the lowest, there were still horrible framerate issues.
I was, however, able to test on a system with a GeForce 8600M GT, and it did play smoothly. So if you can run the game fairly well, you'll be treated to some blur effects when you turn, and there are a lot of charming details. It's also interesting to see what everything will turn into when you convert it. Picket fences become rusty barbed wire, trees become giant steel traps, and people get turned into gloomy, dejected-looking souls."
