That's a bit of a harsh take, especially coming from a creator of a game. I'm not sure how one can come to such conclusions, except by having limited exposure to games. I've noticed that all the titles listed here were rather similar - 3D, action-focused. Those need a particular kind of a story.

The one outlier here is Portal. But it's by no means extreme. Go further, and you reach proper adventure games. Monkey Island? Myst? The Blackwell series? (Okay, I only played the last one, but the writing was on par with decent books.)

Go further and you get less gameplay and more reading. To the Moon has a story that's based on the same premise as one acclaimed movie (can't say which without spoiling). Keep going and you reach interactive novels like Her Story. Maybe it doesn't contain a lot, but after playing it I felt as if I watched a David Lynch movie.

What makes writing good anyway? Believability? Attention to detail? Uniqueness? World-building? Stirring emotions? I'm sure I can find a game that rises near the top of each category... except maybe uniqueness. Ubik is unbeatable there.
