Because these last few weeks I've indulged one of my childhood nerd-dreams, playing some of the old school FPS's online, cooperatively. I'm talking about the various shooters pre-Quake 1 here. Prior to my current stint my only only experience with these old timers online has been playing 2 player Duke Nukem 3D via 28.8kbit (or therearound) dial up modem, which was fun at the time but also incredibly unstable and laggy. These days however, with fast net connections and source engine tweaks that improve net code drastically, setting up a game of say, Doom 2 online is doable even by the most technically challenged such as myself!
