Supermandolini has the ultimate badge of honour for gamers of a certain generation (mine): these sweet SNES or Genesis military-style pins. Now the question is whose pin to sport—the victor's or the vanquished's?
To me, wearing the Genesis pin is akin to having a full Schutzstaffel Death's Head/Sig Runes combo—you are on the side of evil. These will run you €18 ($30). [Supermandolini - Thanks, Emanuel!]
