I disagree. I think the conditions to get a game theory style setup going are quite specific. Always "defecting" against everything (with no warning) and clearing outwards as fast as you can is probably converged upon along many paths, from many starting points, as long as the physics allows it.

Like Wikipedia says, Dark Forest is for people who are limited in tech and resources. Or have a weird sense of ethics, but ask Robin Hanson how long he thinks that would last.
