I remember hearing it pronounced with the hard "g" in the audio CD that came included with A Player's Primer to the Outlands (affiliate link) and raising my eyebrows. But it wasn't a mispronunciation; there was a bit of in-character marginalia in another Planescape book (I can't recall which one) that had someone saying (paraphrasing here) "you're under arrest for pronouncing our beloved Sigil as if it were 'Sijil.'"I love planescape. But I refuse to use the hard g. It sounds ridiculous to me
