		From time to time we see fan projects spring 
up that take advantage of IPs that fans don't actually have the legal 
right to use. Sometime they're served cease and desist letters; other 
times, they're given the support of the IP owners. The latest such 
project involved an attempt to remake Duke Nukem 3D using the Unreal Engine 3. 
After circulating some screenshots of a test map around the Internet, 
project lead Frederik Schreiber got in touch with 3D Realms' George 
Broussard and Scott Miller in order to "start a conversation about the 
project." Schreiber wrote on the Gearbox forums (via Big Download),
 "The shots managed to convice Scott Miller to a certain degree -- But 
the project was only doable if Take-Two would approve it." That led him 
to get in touch with Gearbox, and the project has since been given a 
personal non-commercial license to allow development to move forward.
