The Great Game Trilogy begins with Past Imperative, first published in 1995. I probably picked it up in 1998, a hardcover Science Fiction and Fantasy Book Club mail-away which also contained the second and third volumes, Present Tense and Future Indefinite. As is the way with these things, I loaned the book out to a friend. Anyone who's done the same will know instantly that I never saw it again. Not long ago, I remembered the book and managed to find the same hardcover, 3-in-1 edition, and sent away my hard-earned nickels to the eBay vendor.
