The other important thing was that low sanity should actually create problems. The thing about Eternal Darkness is that it had clever notions to pretend it was deleting your saves or have the main character sink into the floor or explode, but once I understood that these were sanity effects, I felt more motivation to go around with as low sanity as possible to see if I could trigger new ones I hadn't seen yet. I thought they were fun to watch, and they had no lasting effect. It was like collecting trading cards.
It's my understanding that a common complaint among even fans of EDSR that sanity loss would lead to a loss of camera control, which would maddeningly fuck up your attempts to deal with monsters.
Now, given Yahtzee's comments in what I believe were the same week's Zero Punctuation, I could see why that might not be considered a plus, but it does dovetail with Yahtzee's talk about consequences and not with how sanity played out in the game.
I mean, otherwise, fair enough. He doesn't like some features as they were implemented and appears to be attempting to implement them i ways that are more suitable. Sounds like a noble approach.
