At the end of the day, the Pyromania update is a celebration—not just of Team Fortress, but more importantly to you, the TF community! Pyromania in more extreme circumstances can be an impulse control disorder to deliberately start fires to relieve tension or for gratification or relief. The term pyromania comes from the Greek word πῦρ ('pyr', fire). So enter a world of imagination that's so superior to the long-winded world of imagination in books that you'll want to put all of your books in a pile and light them on fire.
