I was comparing GOG sales revenues between different quarters and noticed something baffling. For a couple of years quarterly sales have been at around 30,000, give or take. But according to this table:
https://www.cdprojekt.com/en/wp-content/uploads-en/2020/05/key-financial-data-q1-2020.xlsx
(Sheet: Q2.2019, cell: D155)
According to this table Q2 revenue was 81,108. The 2019 sheet shows yearly total so if we subtract Q1-Q3 from the total, we get 15,839 for Q4 2019. The trend has been quite a steady rise before and all of a sudden in 2019 it fluctuates from 30 to 80 to 30 to 15?

Is this a mistake or what on earth happened in Q2 2019?

Was that when they did that bookkeeping reshuffle between different parts of the CDP Group? Moved Gwent to GOG.com and such.

Could be. Organisational changes could explain such difference. But shouldn't it continue as high as well?

The 80 is for the first half of the year, not Q2. So it's:
Q1: 34
Q2: 47
Q3: 32
Q4: 49
(ignoring rounding issues)

They could do so much better with sub-model. Even if they get 10k subs, thats 100k monthyly. They might lose some games, but I would imagine most of them stay. Steam is so brutally competitive.

Should CDPR try something like that when game is released on GoG, its like 6 month with a price tag, and after that it becomes part of their sub-model?

That would be the death of the store. The point of GOG is that you own what you buy and stays yours, forever. If I wanted to rent games, there are other places that do it better.

More options the better?

Gaming companies can put a game on GoG, if they dont like sub-service, they can GTFO. I personally think its quite damn good deal for gaming devs, most of the time sales are way down at 6 month mark, then they can take an advantage of GoG sub-service and keep things rolling.

That explains it. Thanks.

Renting games that don't have DRM? That's insane. Might as well not have a refund policy.
