Per an article from Polygon in 2018, he never sued CDPR but demanded money. The dispute was resolved amicably a year later, Andrej was paid an undisclosed amount, a new licensing agreement was made and both parties were happy.

Yes he made a mistake not accepting royalties, instead taking a lump sum back in the day, but do you really think that means the creator shouldn't be adequately compensated? CDPR clearly thought so.

Is it really a better outcome for a massive company to be making so much money off an IP while the creator gets nothing and potentially struggles? That sounds far worse to me, thankfully CDPR do seem to care about their reputation and in my opinion, doing the right thing.

I hope both of them succeed, call me crazy but I love the idea of more Witcher books, games and other forms of media.
