Started playing last night, still haven't finished, but will post the result ofc. After following this thread I thought Free Speech and Christo Redentor would be quite important for my win date (supposing that I would win of course). So, following the discussion between 12agnar0k and bhavv, I think for the moment we should interpret the effects of both items, as expressly defined in the manual/game: Cristo Redentor: Culture cost of adopting new Policies reduced by 33% Free Speech: -25% of Policy Culture costs There is no mention in either of the definitions that the reduced cost is meant to be used only when spending future culture. If it was like this: Cristo Redentor: Future culture cost of adopting new Policies reduced by 33% Free Speech: -25% of Policy Culture costs for culture obtained after taking this Policy then I would accept it is presently an exploit. Sadly for my understanding, the game was designed with allowed usage of these effects for past culture, even though you are supposed to receive the discount because you have spent time researching a tech, reaching a certain level of public freedom and hammers for building a wonder. It seems as if up to the moment of time when you have these two, you have been somewhat uncultured. I still agree with 12agnar0k though, and would like to try winning as early as possible without using them.
