mondo84: I think game developers use the same archetype for their heroes because those tall, well built, chiseled, handsome guys just look like the rest of us.
Right?
hedwards: I think that Duke Nukem in particular was intentionally designed as such because it is the stereotypical hero.
Most of the time though, I think it's just sloth on the part of the designers. There are some archetypes that you'll never see as a hero, just as the fat bald guy, but most of the time it's a matter of them not wanting to bother taking the risk.
Duke was born from the "Action movie stereotype of the 90's" thing
The Ironic thing here is that right now he is 10x cooler than the current "Bald space marine" chiche of videogames today
Take any "modern" popular shooter and now replace the main character with Duke Nukem, the game automatically becomes 2-3 times better
