I suppose I need to explain myself. Alas I purchased the game on PC/Steam, Stadia and PS4. And yes I play on all of those, depending on what OS I am booted into and running and which part of my house I feel like playing.
Also, I really think that Steam is the superior platform at the moment in terms of features compared to Epic and GOG, but in this case I think it would be better to buy it in GOG since not only all of the money goes directly to CD Project Red instead of 30% for Steam, but also there's some goodies if you buy it in GOG...
Anyway, I think if you bought the game 3 times you more than make up for that 30%.
