For those that don't know, quite a few of Duke's quotes were originally spoken by Ash in Evil Dead 2: Dead by Dawn and Army of Darkness, including: I believe there are a few more, but they escape me. When I rewatch the Evil Dead trilogy, I'll write them down and then add them here. Anyway, Ash was the original badass that said these lines, but Duke is cool enough that I'll let it slide.

And just as a side note, even though Doom was multiplayer, I think Duke3D was really the first game to actually stress balanced multiplayer gameplay. Quake would later take that a step further, and bring it to the internet, but the first exciting multiplayer FPS has to be Duke3D. Perhaps the fact that my coworkers and I would map out the office in the (included) Build editor and then Duke it out in our boss's office had something to do with it... not sure. I suppose that's another thing that Duke3D helped pioneer -- included level editors. Even if you didn't care for single player or level design, Duke3D is a great investment for those that just enjoy LAN parties. It's up there w/ Quake and Descent when it comes to multiplayer.
