I don't have a lot of rare stuff in the collection yet, although I do have games that are only in my collection such as a Saturn demo disc, cube battler, and 3d shooting maker. However, what baffles me is that I'm the only person who has a copy of Front Mission 2 on this database, especially since given how for being a srpg Japan only release, most of the mandatory text is in English, and there are around 530,000 copies sold, and its not very expensive either.
