The Church of Gaming started out as a minor chat Web site based on the religion from Ctrl+Alt+Del but split into its own multiverse with multiple stories and characters. It currently follows Adam, Austin, James and Scott as they lead the Church of Gaming. The stories can be read at http://churchofgaming.wetpaint.com/
Only One Name: Austin, Adam, Scott, James, Tristan, Domerix, Dillon...
Our Zombies Are Different: Played straight and subverted. There are "normal" zombies that make up the bulk of the Swarm's footsoldiers, but most of them come from games with very diffrent zombies- the Flood, Fallout's Ghouls, Tanks from Left 4 Dead, Headcrabs from Half Life, Manny from Grim Fandango, Re-Dead from Legend of Zelda, and much more.
Physical God- The Gods can be directly interacted with and even killed with rather mundane methods.
Austin kills the God of Sport Games. With a single headshot from a handgun.
The Multiverse: The Church of Gaming takes place in Earth-21. You're reading this from Earth-1.
