  ==Publication history==
  On 24 April 2007, it was on George R.R. Martin's website that Green Ronin Publishing was producing a new line of ''A Song of Ice and Fire'' RPG products, unrelated to the earlier Guardians of Order ''A Game of Thrones'' effort. Robert J. Schwalb designed the ''A Song of Ice and Fire Roleplaying'' game, which was previewed in 2008 and published in 2009; this was his last project for Green Ronin before he moved over to Wizards of the Coast. The Green Ronin game, titled ''A Song of Ice and Fire Roleplaying'' (''SIFRP''), went on sale on 10 March 2009: it uses a custom game system and does not contain rules from either the d20 or Tri-Stat dX systems.
