Don't know if anyone has seen an example of it so here it is:
Normal mapping is a method where by the normals of a mesh are given more detailed lighting information by means of a bitmap image. This give the mesh the appearance of more realistic lighting and more surface detail. If you see some blocks it's because Sega is using an entirely new, bleeding edge graphics technique. We're talking low polygon models, which allows them to bump up the detail and frame rate way beyond current standards, and with Normal Mapping, we're talking about the same look at polygon models that are literally a generation beyond Madden 2005. Here's an example from the upcoming Far Cry:

OK, I get it. The top picture is showing the figure composed of 250,000 polygons.

The middle picture is showing how the figure would look at 1500 polygons.... And it isn't good.

Yet in the bottom picture, we see a NORMAL-MAPPED 1500 polygon figure side-by-side with a regular 250,000 polygon figure... and they look nearly identical.

So the advantages are obvious. If you can get basically the same results using less than 10% of the polygons....

... Maybe THAT'S why they can sell the game dirt cheap!
