Interesting. I never found out how to pronounce Sinéad O'Connor, so she turned into some kind of non-person for me. Maybe like Nyarlathotep.

Gog for me. Saying out the letters seems bizarre to me.

I always say GOG, even when it was an acronym.

GOG, not gog, I always shout it out loud.

I've literally never seen anyone say gee oh gee, unless they were either gog staff or paid industry shills.

Seeing "GoG" really gets my goat.

Depends on my mood. Sometimes "Gog" sometimes "GOG" or "gog" or, yes, even "GoG" or rarely "the place formerly known as good old games".

edit
Similar with outspoken. Sometimes "Gog" sometimes "G - O - G" and sometimes even "G - O - G dot com".

Calling G-O-G sounds weird to me.

I always say 'gog'.

I can't forget TheEnigmaticT's "This Week on GOG". It'll always be gee-oh-gee for me. At least if I say it in English in my mind.

so the gog staff says g.o.g.? so that's the official way to say it?

Yes, I suppose so. Every single time you hear someone from staff say the name in one of their official videos they will say gee oh gee. Head honcho Marcin Iwinski says gee oh gee, which pretty much makes it official.

man, so I've been wrong the whole time!

I'm not sure I can get used to the official spelling so quickly.

Officially -- by which I mean publically -- yes, they've always said it as initials. However, I've seen a couple of GOG/CDP staffers post semi-recently (mostly on Reddit, but I may have seen one here) that around the office, among employees, they sometimes (or mostly, when conversing in Polish) say it as if it were a normal word, rather than pronouncing the English names of the individual letters.

And so begins the traditional "But what do the initials stand for?" portion of the thread.
I'm going with gross octogenarian grannies.
