On the topic of Chrono Trigger, I may as well showcase a few auctions.
eBay seller route001 has a ton of nice promo items from Japan. It’s definitely worth looking through the items he currently has available. There are a few Chrono Trigger items there that caught me eye though.
First, he has a bunch of Chrono Trigger Prism Cards. I have never heard of, nor seen these before, but the seller states: This is a card which only the person who did reservation purchase of “Chrono Trigger” can get.
This does coincide on the 1995 copyright on the card, so I guess it does make sense.
They also have an amazing Chrono Trigger keychain set. A little too expensive for my tastes, but nice nonetheless.
