Definitely a more philosophical view on what sales are doing to destroy some games. What I took away from it is that the importance of word of mouth as a way of promoting games doesn't reach people who are waiting for sales as much since their reason for buying the game is because of its low price, rather than from a desire to play it and experience it, and then end up sharing their experience.
I agree with that, but then again, if someone wasn't ever going to buy a game at full price to begin with, then you never access the possibility of a player promoting their game through social means. Ever.
If anything, the negative parts would've come in other forms through the internet and globalization. I have so many games. Soooo many games that even before Steam, largely, popularized their blowout sales (Hey, Black Friday's existed longer than the internet, guys), that my library is just larger than the time I have to play every game.
He's definitely got a point, but I don't think it overrides the positives that sales have given to most creators that've otherwise not seen social or monetary returns.
