He co-wrote the computer game Savage Empire, which was named Best PC Fantasy RPG by Game Player magazine in 1990. He authored the Rules Cyclopedia 1991, the second revision to the Dungeons & Dragons game. He branched into writing, and by the mid-1990s had two novels under his belt.
He began writing on the Star Wars X-Wing series in 1997. Allston produced a new edition of Champions for Hero Games in 2002. In 2006, Allston launched the The Legacy of the Force series with a hardcover entitled Betrayal.
