This is the internet age. Se7en is pronounced Seten.

I always used the dog-like gog, never gee oh gee.

But then, gee oh gee sounds a bit better and more comprehensible.

It's an abbreviation, and thus each letter should be pronounced seperately. Periods or no periods really makes no difference.

Based on a semester of phonetics and phonology studies a few years back, I'd also say that pronouncing each letter seperately is in fact easier than saying "gog" (rhymes with dog) because humans are inherently lazy speakers and will tend to use sounds that are produced in the same area of the mouth if possible, and saying each letter seperately achieves this, while "gog" does not.

EDIT: Oh and "gog" sounds completely retarded.

I usually plump for 'The real O'G'

I don't care about rules of abbreviation. If one pronounces it as GOG, they can say things such as "Kneel before GOG!" Laughter ensues as people not wise to Superman II quotes stare at you with a puzzled look.

Pronouncing it Gee-oh-gee sounds really pretentious, as though your expecting whoever your telling about it to know what it means. Its also clunky and awkward to say. I prefer gawg. When I heard Marcin on the video I wondered if they had even considered pronoucing it gawg, I just assumed everyone already did. It just seems a lot easier.

I'd figure since pronouncing it "gee-oh-gee" is three syllables and "gog" is only one that "gog" would be easier.

And "gog" might sound retarded out loud but I've never spoken it out loud, just internally. The same way I read "lol" as "lawl" or "rofl" as "roffle" and so on an so forth. And yes, I really am that lazy. :D

poor, poor podcast

on topic: GROG -R

Actually, it's kind of comforting to know I'm not the only one. When Iwinski said it like that on the video I was like "You mean I've been saying it wrong for the last two years?" but nope! Turns out I'm in the majority now.

Mostly say G-O-G (gee-oh-gee) sometimes I will opt for Good Old Games though, there's something with a sport with the same abbreviation in denmark so it helps with the understanding

I always pronounce the word, not the letters.

Syllables has little to do with it (obviously you'd naturally opt for 3 syllables over say 17, but 1 vs 3 makes no difference). It has to do with where in the mouth the sounds are made, and how much movement of your speech-related muscles is required.
Saying every letter seperately requires a little movement of the lips and a slight movement in the tip of the tongue, switching from "g" to "o" to "g" again.
Saying "gog" requires you to open your mouth quite a bit more to fully voice the "o" - at least if your using American English phonology (in which case, as you've all noted "o" is pronounced "aw" while saying "gog"). It also requires you to make a sound at the back of your mouth to mark each "g".
Overall the mouth works a little harder to say "gog" than to say each letter seperately.
Interestingly enough, the opposite is true for "lol"

EDIT: Oh and what's up with 3 people from Denmark posting right after each other... while it's 7 AM in Denmark? (I'm excused, I may be Danish but I'm in California)

So lazy that they would only say one syllable instead of three, right? In fact, it's just as long to say Good Old Games as to say gee oh gee. Also, "gee oh gee" just sounds out of place and weird.

Saying each letter seperately sounds perfectly natural to me. "Gog" sounds weird. And you need to read the post just above your own.
