To those saying the G is silent, I think you would be right under normal circumstances, but in this case, I don't think you are. Since GNOP is PONG spelled backwards, I think you should essentially [i]say[/i] PONG backwards. The 70's board game [url=http://www.youtube.com/watch?v=GX2bqI--c-k]GNIP GNOP[/url] was pronounced with both of the Gs as it was a play on PING PONG. I think the same applies here. Since you pronounce the Gs with the words normal forwards spelling, you pronounce the Gs in the backward spelling as well. Of course, it's largely up to Bungie how we should pronounce their game, and I've not heard either way from them. [Edited on 12.08.2012 7:30 PM PST]
