It is unclear whether this designer database entry accurately reflects the identity of the designer(s) of the games currently linked to this entry.
Michael Matheny is credited as designer of Circus Maximus from Battleline and Avalon Hill, games which are linked to this entry.
Michael S. Matheny, aka Michael Scott Matheny (whose name is not reflected as an alternate for this designer entry) is credited as the designer of several Yaquinto games which are linked to this designer entry.
I have not been able to confirm that a Michael E. Matheny was listed (as a typographical error or otherwise) as the designer in the physical documentation of any of the linked games.
A thread regarding this question has been posted in the Wargames forum, and this description will be updated accordingly once the discrepancy is resolved:
