My channel (MetalSmasherGaming) is not fully centered around Doom, but I have played the classic Doom games for my channel, including the Xbox Live Arcade versions of Doom 1 and Doom 2 (as well as No Rest For The Living), as well as the Plutonia Experiment half of Final Doom. In fact, I'm actually working on replaying through Plutonia right now in Solo-Net as a personal challenge.
