Visually, NCAA Final Four 2003 isn't among the most appealing... Lighting, ground reflections and specular highlights are realistic, but the team player models are rigid with unrealistic motion and slow reactions. Most unacceptable are the disappearing polygons on different parts of the court - almost as if the court was programmed into the graphics engine instead of drawn... and again, the people in the crowd are obviously bill-boarded textures (God, I wish these sports games would get that straight).
There is something to be said about the sound effects: shoe screeches, bands, and crowds all sound pretty realistic, thankfully. There is something I haven't quite figured out about the music though. At times the theme songs are played by real school recorded marching bands which sounds great, and then other schools seem to have pre-synthesized music. For some reason the synthesized themes always stand out like a bad note...
