Yes, I was aware that they rebranded to just "GOG" but left it that way for familiarity. That's how most seem to remember it.
GOG being Polish is a little more complex. I noticed the Cyprus address at the bottom of one of their products while researching the article, so I thought I'd take a look and here is what I THINK reality is. GOG Ltd is a Cypriot company (Florinis 7, Greg Tower, 6th floor, 1065 Nicosia, Republic of Cyprus) and wholly owned subsidiary of CD Projekt out of Warsaw. All of the games distribution and payments are evidently run out of Cyprus. Earlier this year CD Projekt created GOG Poland and on 22 May 2017 drew up draft documents to merge GOG Ltd with GOG Poland and move all operations to Warsaw. I couldn't easily find a record of approval and merger date, so I left it as Cyprus. I figured that would be less confusing and it sounds spiffier anyway.
If you are interested, here is a link to the merger document - http://files.gog.com/company_reorganiza ... _PL_EN.pdf
