Duke Nukem 3D was built on the 'build' engine, which was built by a super cool 18yo called Ken Silverman http://advsys.net/ken/ .
Back in the 90s John Carmack was asked "If you could just hire anybody from the 3D world, who would you hire?", and he named Ken http://advsys.net/ken/carmken.htm
Thanks for the link! This really took me back to the games I grew up on that influenced me (haven't heard the names ROTT or Redneck Rampage since the 90's)
