Yea, it sucks that someone who made 2 of the best games ever had troubles in making a 3rd one for so many years. It would have been cool to see a Bioshock 4. I think games directors should stick to great franchises if the previous entry was great.
Kojima is another one. He used to be the no. 1 hyped up games director of the 2000s-2010s. But he started burning out by the time of MGS5 and this project was troubled. He was tired of making Metal Gear games for so long, despite their exceptional quality. He let his feelings slip into the gaming press. He made Death Stranding (to good but not great reception) and has kind of disappeared into the background. The more years this goes on, the more his star will fade.
