Those Sony leaks are insane, Spider-Man 2 cost over 300 million to make and Miles Morales which is basically DLC with reused assets cost 100 million to make. Their budgets are way too high Imo, we already know that God of War and Horizon cost over 200 million thanks to the FTC leak.
I doubt that many of the XGS games reach that high outside of Halo and Gears.
