This is a generic company entry intended for all self-published board games, video games and pen-n-paper RPGS.
A self-published work is produced independently, without the involvement of an established publisher and at one's own expense. This puts the author in full control of the entire process, including design, price, distribution, marketing, and public relations. The author may do all the work themselves or outsource some of the work to companies which offer these services.
If the designer of a self-published game has a publishing brand, then a publisher listing should be created for that brand, with that brand then being added to the BGG game listing and the "self-published" tag being removed.
