In terms of SP games in my experience the very best ones that leave a lasting impression are usually those with a good plot. Yes characterisation is important and you can get away with a mediocre plot if the characters are strong, but most of the "WOW, that was incredible!" games are strong plot wise e.g. Bioware RPGs.
Reading that article it seemed to me that they have placed too much emphasis on the specifics of what players remember. Just because players don't remember a full plot, doesn't mean to say it didn't help to frame their enjoyment of the game. And characters being memorable in some ways is just a manifestation of the part they play in the plot (e.g. Glados, Fontaine etc).
