This is an open-ended crowdfunding project for Hardcore Gaming 101's newest book, which is devoted to "101 rare, weird and important Japanese video games".
If you aren't familiar with HG101, they're best known for their lengthy and informative articles about all sorts of games, including many Japanese ones. They have published a number of books in the past, devoted to everything from adventure games to Data East arcade classics to the Famicom Disk System.
Although this project is open-ended, they will cancel it if there isn't enough support. I would love for this new book of theirs to be published, and if you do too, please support it!
