I searched for this and couldn't find anything on this. Anyway on to the topic.....
As on late I've been thinking about expanding my small GB & GBC collections. I looked through the guide on which titiles that are the hardest to get and lots on titles are R5 and R6 but I couldn't find what are the hardest to get titles for the systems. So what are the hardest US released GB & GBC titles to get? A list would be helpful when looking for games at game stores and flea markets. Thanks in advance.
