camera problems

hi everyone. i was wondering if anyone could help me with my camera problem. i would like to know how it is possible to make camera angles that follow the character almost in first person but not quite, just right behind them. i don't know if u have all heard of legacys:tides of serpent, or the world of warcraft 3d demo that just came out. but in those maps , the camera follows the character around , and its right behind them. plz , if u can tell me step by step how to do this. ty in advance, and ty for all for the help that ive been getting in my other threads. ^_^

This really goes in Cinematic development.

As for the question, create a really low camera and set its x/y to right behind the unit.
