I'm not Stargate's biggest advocate. I've mentioned before that I just quite didn't 'get' into the show during its run on premium cable and the SciFi Channel (now Syfy). I caught episodes from time-to-time; but it was honestly only just earlier this year that I binged my way through all of Season One. There were some small gems in there. I've always enjoyed good characters, but I struggle with stories that are either too routine or too overcooked ... and I found much of SG-1 a bit thin on the bones. Still, I'll persevere as time permits and continue the journey.
Alas, the beloved franchise has lost another: Cliff Simon. With twenty-six professional credits to his name, the SciFi saga was definitely one of his biggest accomplishments in genre, with appearances in fifteen episodes as well as the Stargate: Continuum telefilm. Fans have flocked to the Information Superhighway with stories of their memories with him, so much so that it's clear that the actor was dear to Stargate fandom.
As I always point out, we'll always have the time on flickering images to remember him by. Make sure to wish the man godspeed when you can today.
