We agree more than this transaction has implied. I welcome
cognitive models, too. I look forward to the insight they provide,
and am eager to replace my faulty intuitive models of a given set of
players' minds.
Let me try anew: Cognitive psychology is a welcome inclusion for
gameplay analysis, but it does not yet exclude modeling the
structure of a game. Even the cognitive scientist Allen Newell used
a game tree to model how humans play chess. Of course, as all of us
agree, humans and computers don't use the same algorithms to search
a portion of the game tree. But understanding game structure is
still a prerequisite to understanding human strategy. For example,
in Newell's study, players used what he called progressive
deepening, which in his own words was a modified depth-first search
on a game tree.
You know the details better than me. As an outsider looking in at
cognitive science, I see the field, if anything, including quite a
bit from computer science. I could not recommend exclusion of game
trees and tree algorithms--not until demonstrating the advantage of
excluding these models of gameplay. I welcome that demonstration or
any other evolution of the science of games.

You'll not argue that with me! :) Of course tictactoe is more
interesting than rock paper scissors; but that hardly matters after
having solved tictactoe.

Then we agree above, too: Solved tictactoe and solved RPS are chores.

No, of course not. The comparison mirrors my own examples of
calculus and FPS. I wondered if NP-hard is necessary for fun--not
if NP-hard is sufficient for fun.

Yes you're right; my generalization was false. NP-hard is not
necessary for fun.

...

Yes. And the example elucidated the principle excellently.
