Glenn's third collection of poetry, this work received the Montana Award for Poetry and the Montana Readers' Choice Award at the 2003 Montana New Zealand Book Awards.

He was the first poet to be awarded the Readers' Choice Award in a readers vote. In October 2006, Playing God went Platinum with Booksellers New Zealand, making its way onto their Premier New Zealand Bestsellers list.

It is the only poetry collection in New Zealand to make it to Platinum, meaning more than 5,000 copies of the book have been sold (to date more than 10,000 copies have sold!).
