"As for the encyclopedia, well, it seems that we might end up going through the back-door on this one, as we’re in serious talks with a RPG 20D group who are keen to adapt the Malazan universe to a game. If this goes ahead, well, it will of necessity involve a release of all the relevant maps and game-notes presently occupying a cardboard box in my garage, and those from Cam as well. Said project demands full disclosure, don’t you think? Although, that said, the eventual release of everything could end up as instalments, expansion packs, etc. Still, it does mark an opening of the flood-gates."
No deal has been signed yet, so nothing is confirmed, but Erikson indicated that he and Ian Esslemont would release all of their background material, including maps, for use with the game. No word was given on which company was interested in publishing the game.
