Dedopulos was born in Winchester, Hants on the last day of the 60s, and graduated from University College, London in 1993 with a degree in Anthropology. He has been writing professionally ever since, often in conjunction with more traditional editorial day jobs. Early in 1995 he joined the Glasgow office of Seattle games giant Wizards of the Coast to work on their dystopian future-horror game SLA Industries. The game line was dropped just before Christmas that same year, and after a period of freelance work, he moved to London publisher Carlton Books, where he worked as Executive Editor.

In 1998, Wizards of the Coast gave all rights to SLA Industries back to the original creator, Dave Allsop. Allsop and original SLA designer/co-writer Jared Earle invited Dedopulos to join them in reforming the original company that had produced the game, Nightfall Games. Dedopulos worked as de-facto Managing Editor of Nightfall until the company's publishing partner, Hogshead Publishing, closed its operations in 2003 [1]. He has been writing and freelancing since then.

Dedopulos's publication history includes some 85 works as of 2007, with almost 80 more as editor. A selection is given below.
