Has anything changed since the Fall patch, because I find science victory harder to come by and find it more worthwhile to invest in Culture. Despite having most science techs I am lucky if I get SV by end of game unless I get an engineer or some additional scientists. I was playing on King difficulty until around end of year and winning mainly by warmongering. Now the game feels very different, and I have to drop down to Prince. I think science has been nerfed but when I am not sure.
