I think I might break my golden rule and not buy this on Steam. I'd like to support CDPR by giving them 100% of the monies on GOG.
Yep, that's what I'll be doing, I have Witcher 3 and Thronebreaker on GOG for the same reason.
I'm almost tempted to pre-order, but that's something I rarely do, especially so far in advance. The 30% off at their merchandise store could tempt me, but looks like it expires at the end of the month and with so much out of stock that seems a bit pointless.
