I'm sure that thsi has been talked about before, but I was just reading some others' "Finds of the Year" and thought that everyone could just throw their great, rare (either a personal rarity -- a game that you have been looking for for ages, or a book-rarity -- one that is generally accepted to be rare) finds in the wild here.

Personally, I have had a shitty year for rare finds, and the only thing that can fit into this categary for me is PSX Terry Pratchett's Discworld (R5) which I have not been able to find anywhere (and I wanted it) and is one of the rarer items in my collection (my collection is filled with commons mainly...)
