I can't remember when I started to collect these but it was definitively several years after first buying my Lynx. I've amassed most if not all of them from ebay. Without this site I really wouldn't know whereto find them. They are seldom listed so I'm always on the look out for them. I'm not entirely sure how many there are in a full collection or indeed how many of each 'title' were manufactured.
They seemed to be popular in France. I'm not sure if this was the country they were released in?
