It appears different badge combinations produce different text in the serial console game. There are the text additions I've seen from diffferent combinations, and the rooms they appear in:

• Human:Human = "The stranger next to you accidentally knocks your ramen on the floor.  Great." in the ramen room
• Human:Goon= "The guards around town are in a foul mood.  Best to stay out of their way!" in the business room
• Human:Speaker = "Graffiti on the wall says 0x9E1CE2C2F6FBFE198637E6F10B957DDD50A7874177A51E" in the arcade room

Hex values seen so far:

• 0x2BFC8E2B3561C04FBBC73FA43D5D96540D0AA008B30924CE47DA0EC67530D3
• 0x9E1CE2C2F6FBFE198637E6F10B957DDD50A7874177A51E
• 0xFEED B0B0 DEAD BEEF

Ive had no luck decoding them... missing something. Its also worth noting all badge types show these same hex codes, just in their respectively themed rooms.
