Vili the Warrior, a mascot for the University of Hawaii, has sued EA for $75,000. He claims that EA used his character without permission on NCAA Football '06.
Lawsuits such as this one are common (although we doubt EA has previously been sued by a half naked guy covered in war paint). Earlier this month,Sony won the first stage of a lawsuit involving Sony's use of an ice cream truck in Twisted Metal (see our coverage here ). The risk of a lawsuit makes copyright and trade-mark clearances an extremely important part of game development and production.
