I'm sorry, but you're just not hardcore unless you have one of the following tattoos:
-Awesome Possum
-The instruction manual page that describes Fighting Street's controls
-Bubsy
-Strider from the added stage in the PCE ARC CD port (with orange skin)
-Bravoman (with sound chip embedded under your skin that keeps saying "Bravo!" again and again 24/7)
or best yet:
-The stoked guy from the TG-16 box!
