Amazon is continuing its monthly run-up to Return to Monkey Island by offering yet another Monkey Island title for free: Escape from Monkey Island. And look, I don't know how these newfangled Prime Gaming services work, but presumably, you log into your account and claim the game. Presumably. It's not like one can have too much Escape from Monkey Island -- editor Thrik recently claimed it to be "the most beautiful game in the series," after all. (Might have been paraphrased.)
