I think it's a bit sad that Duke has turned into a meme. Right now he's just brought up to poke fun at DNF, or at some of the admittedly more questionable aspects of 3D. I think there's a lot to love about Duke Nukem 3D even today. It's cheesy, it's a little sleazy (greasy, even), sometimes maybe a hint creepy (though less than people think, ultra-misogynist is more of a DNF thing, 3D is usually fairly tongue in-cheek about it), but it's still got a lot of charm and personality in its every little detail, back when that really wasn't a thing in the genre. Plus, it's still just fun, y'know?
