When I trade with someone, I always try to get SPECIAL WEAPON versions of the item. People normally identify their weapons, including before they dupe them. So to me, SPECIAL WEAPONs establish some degree of trust that it is not a copied item.

It certainly is true that you can copy SPECIAL WEAPONs - and even turn existing items including Monomates into them - but it's very rare.

Also, I like looking for the mid-range rares. Everyone and their mother has a Lavis Cannon and an Egg Blaster. But things like "Suppressed Gun" and the fake "Agito" really are rare.

I've learned to adjust to the amount of cheating that goes on.

I may make cheat codes for PSO (my newest one being a code allowing you to play any difficulty level offline), but I'm actually not a cheater. The only duped item I had until yesterday (when Sega banned them) was a Devil/Technique-- I made for self-defense.
