I don't know if I've linked to Overcoming Bias before or not. It doesn't deal with gaming, but is interesting and sometimes deals with tangential items of interest (especially to game theory).
Today they are talking about Newcomb's Paradox (which I first encountered in a math class in middle-school. Thanks, Martin.)
And the following jumped out:
Nonetheless, I would like to present some of my motivations on Newcomb's Problem - the reasons I felt impelled to seek a new theory - because they illustrate my source-attitudes toward rationality. Even if I can't present the theory that these motivations motivate...First, foremost, fundamentally, above all else:
Rational agents should WIN.
Don't mistake me, and think that I'm talking about the Hollywood Rationality stereotype that rationalists should be selfish or shortsighted. If your utility function has a term in it for others, then win their happiness. If your utility function has a term in it for a million years hence, then win the eon.
But at any rate, WIN. Don't lose reasonably, WIN.
