  This is an attempt to formalize the conditions of possibility for free,
libre, open access to scientific knowledge within a game. The challenge is to
enunciate the terms under which agents participating in the Grand conversation
of science would be willing to open share, exchange, negotiate or surrender
their contributions, considering their corresponding intentions, goals, beliefs
and expected utilities. Many conclusions can be drawn from the game here
described. We have made many simplifying decisions along the modelling process
that must be taken into account as a determining context for those conclusions,
of course. It can be safely state, however, that under the current conditions
of the game, Editors will keep betting on Toll Access, knowledge distribution
models even if all the other Academic agent go for Open Access.
