I just wanted to put a plug in for The Spiel podcast, that did a hell of a job laying out España 1936 and describing gameplay in fine detail (episode 72). Given their recent forays into Twilight Struggle and 1960 and now a play of España, it appears that they are standing upon the edge of the precipice, looking down into the depths of wargaming and considering taking a step forward.
Worth a listen for anyone who has not gotten a chance to sit down with the title. Their unique use of the album art feature in m4a format means that you'll need video to get the deluxe effect (iTunes on your PC is sufficient) but even the mp3 version is valuable.
