Wham worked a variety of odd jobs during his early adult life. After serving four years in the U.S. Navy, he worked for the Guidon Games hobby shop in Maine where he got his first game, a variant on a Civil War naval miniatures campaign, published. One of Wham's books was published in the same series of books from Guidon Games that began in 1971 with Chainmail. In 1972, Wham got a job with Don Lowry at Guidon Games, in the shipping/layout department of Campaign magazine; there, he co-authored a set of Civil War naval miniature rules, Ironclad. Afterwards he became a prison guard in his hometown, then held an office job in Denver.
TSR
In May 1977 he began working for TSR, Inc. at their Lake Geneva, Wisconsin headquarters as a general office worker, the company's 13th employee. After running the Dungeon Hobby Shop for a summer, he was moved upstairs to the company's art department. Wham worked with Dave Sutherland and Dave Trampier on the original Monster Manual. Wham began doing some creative work for the company, contributing a handful of illustrations for the original AD&D Monster Manual, including the creature called the beholder. He also made a deal with Tim Kask, editor of The Dragon, to do a game in the centerfold, called Snit Smashing; this led to other games in Dragon, including The Awful Green Things from Outer Space. These games, printed on cardstock and included in the centerfold of the magazine, usually featured artwork supplied by Wham. Notable games published this way include:
Snit Smashing: Originally published in Dragon #10. In Wham's first game for Dragon, tiny creatures known as Snits run outfrom the sea and try to procreate while avoiding the giant blob-like Bolotomi, who smash the Snits out of boredom. Players alternate control between the Snits and the Bolotomus, attempting to make their own Snits reproduce faster than those of their opponent.
Snit's Revenge: Originally published in Dragon #11. In the more famous follow-up to Snit Smashing, the Snits set out to finally kill the elephantine Bolotomi who are smashing them, by invading their bodies and shutting down all their internal organs. This was published as a separate boardgame by TSR in 1978, and is now published by Steve Jackson Games.
The Awful Green Things from Outer Space: Originally published in Dragon #28. A game of green aliens invading a spaceship. This too was eventually published as a separate game by TSR and later published by Steve Jackson Games as well.
Search for the Emperor's Treasure: Originally published in Dragon #51. Players take the roles of adventurers searching a fantasy empire for the emperor's scattered magical treasures. A revised edition was included in a box set called "The Best of Dragon Games", 1990.
File 13: Originally published in Dragon #72. A game about designing board games. A second edition was reissued in "The Best of Dragon Games".
King of the Tabletop: Originally published in Dragon #77, this is a game in which people create their own kingdom from little cardboard chits representing land, characters, and events. Also expanded and published commercially as Kings and Things by West End Games, Games Workshop, and later, in a German edition, Pegasus Spiele.
Elefant Hunt: Originally published in Dragon #88. Great White Hunters travel through deepest, darkest "Aferca" with the help of natives to capture as much live animals and ivory as they can to sell for profit.
After TSR
After TSR, Wham collaborated on books with Rose Estes, and did his own novelette in Christopher Stasheff's The Exotic Enchanter. More games followed, including Kings & Things, the card game, and Iron Dragon. Later efforts include a reprint of Snits and Awful Green Things from Outer Space from Steve Jackson Games, and Planet Busters by Troll Lord Games. Wham designed the board game "King of the Tabletop" with Robert J. Kuntz, which was published in Dragon #77 ; the game was later expanded and rereleased as Kings & Things by West End Games, and was an Origins award-winner. Since leaving TSR, Wham has designed many more games, including collaborating with James M. Ward on the board game Dragon Lairds, published in April 2008, and Feudality published by Z-man Games Inc. in 2011.
