Nathan P. Butler has contributed in small ways to tabletop games (board games), typically either as a playtester or a rulebook proofreader. (Proofreading has typically been informal assistance that led to a rulebook thanks of some kind.)

Nathan has also “appeared in” three board games.
(Left to right: Nathan as the “Disposability Rater” character both the Government faction in Master of Wills’ Novus Community Expansion and the Old East region in Thornraver: Battle for Solus, both from Stormcrest Games, and as “Lt. Nat’han” in The Last Command from Sentient Games)
He also has a custom card for Heroes of the Sanctum, but that probably doesn’t count, as it was a gift for being Firetap Games’ first Kickstarter backer and only provided to Nathan (not in the released game).

His son has been name-checked in Shadows of Kilforth from Hall or Nothing Productions.
