The new DOOM might be getting all the attention right now, but let's not forget the Quake. The original DOOM may have been a landmark game, but it was Quake that refined the formula, made it fully 3D and gave birth to the likes of Capture the Flag and Team Fortress.
Fire up the doco now on YouTube and listen to the sultry British tones of Ahoy's Stuart Brown, who you may remember from other such videos as the history of miniguns and (sea-based, not Mark-based) piracy.
This thing hits heavy nostalgia territory for me. My fondest first-person shooter memories are definitely Quake-saturated. I tinkered with DOOM, editing WAD files and hacking the executable to add my own weapons, but it was QuakeC that opened the floodgates to my modding career.
In fact, I still have Quake installed with a bunch of home-made mods sprawled across countless directories. I also have Operation Bay Shield, which I believed was the height of comedy back when I was a teen.
Anywho, let's all fire a rocket in memory of Quake... preferably a physically-shaded one in DOOM.
