When you do the first story mission in Belleville, France, Pox will start 
talking about video game ideas. Crypto will say, "You're a plumber, but you 
don't use plumbing stuff to kill your enemies, you just jump on them" (a 
reference to the Mario series), "You're a really fast hedgehog" (a reference to 
the Sonic series), and "You're a space marine on a planet with a ring around it" 
(a reference to the Halo series). Pox will say all those ideas suck and then 
makes up his own idea.
