It was an interesting video, but he lost me when he started complaining about some games feeling too 'gamey' by curbing to good pacing or rewarding exploration deliberately.
Thief4 may be a bad Thief game, and a poor game in general and so comparing to earlier Thief games makes sense, but using it as a springboard to complain about design choices in other games of completely different types waxes as "Not all games are designed how I like it, bluh bluh".
Sure, if you're making a game that's designed around getting the player heavily immersed in the world, then that's awesome. But if that's not the point or style of the game, then why would you do it that way?
Everything he complains about can be implemented totally properly without weakening the gameplay experience, and has been in different games. It's a conflation of 'some games do a poor job of ____, and so all AAA games must have failed in this regard', which is impressively weak reasoning.
