Hmm, money matters no? They have 400 people working on this game, lots of games are made with staff of 150 to 200. I think you guys are underestimating this project.
I think you are overestimating CDPR's resources. They don't have the money to throw around like EA or Bethesda.
Their own consumer friendly approach is hindering them in this case. They are not in the red, but their profit margin is not really that high ($28.6 million in 2018, with 2019 likely be lower).
Cyberpunk may be CDPR's biggest project yet, but it's far from the biggest ever. It will be a good, probably great game, but it's unlikely to revolutionize.
