The Superliga Bundle has been published!
You can find it here:
The first two books are interchangeable, being slightly different versions of the main rules. The last two books (Intrigue and Expertise, as well as Compendium of Marvelous Things) work with either the first or second. All of the books have been constructed from the sweat and determination of yours truly and all of them have been enhanced with the fine visual resources found at fromoldbooks.org to give them a classic look.
Sample, enjoy and please, do provide feedback!
