I'm pretty excited that this will be better than GTA IV, because:
A) It doesn't seem completely grey like Liberty City.
B) It doesn't seem completely depressing like GTA IV.
I didn't like the GTA IV plot because it never really went up, it just went downhill. To use a quote from the final episode of Flight of the Conchords: "Ours is a story about two guys that start at the bottom, continue along the bottom, and end up at the bottom. It's a rags to rags story."
