More than that, it's logistically untenable. Inevitably, when teams get too large, how do you keep tabs on accountability? I suspect this massive team size is a consequence of the perfectionism streak Naughty Dog has.

I wish we could have so many people working on something and it turns out great because I'm all for collaboration in spirit - the problem is too many people as part of the larger team and smaller units. Suppose for example that you have too many people in the art department; you will very often come up against fiercely competing visions for how things should look. That competitive vision will cause friction between team members, team doesn't work as a unit, the back and forth can further delay parts that the other departments are waiting for, etc etc.

A 200-person team says, to me, that we need to scale back game development. Even if it means we go back to PS2 era costs and scale, why not? Those games are still great fun, the budgets were in check, and you could literally break the 200-man team into like 10 20-man teams working on different projects.
