Quake has been around a long time. I still remember playing some custom maps and even doing some mapping way back when I was an early teen but outside of a few map packs I stumbled across over the years I'm not very familiar with a lot of what's out there. When it comes to one of my other favorite games, Doom people recognize names like Scythe and Hell Revealed or Sunlust and Sunder. It has a large enough community that things are well documented and easy to find. Sadly when it comes to Quake things are a bit different. Information is much more scattered and the amount of community content is far smaller so the average person has to do quite a bit of digging. I was glad to stumble on this site and hope it grows to fill that gap. For the sake of sparing myself some digging along with the hope of creating a thread that may also help others I'm interested in anything that has some historical significance, offers a good deal of quality or innovation, is generally interesting in some way or is just plain fun. So what are the big names out there? What's some good classic stuff? What's some good modern stuff? What would you consider essential? Or anything else you think is noteworthy.
