This is my first multiplayer game since getting NFP. About every other turn or so, they go from make 2-7 gp points in science, which is consistent with the game era, to suddenly making like 25-27 points per turn. This will stick around for a turn or two, then go back to the original value, and happen over and over again. I'm playing maya, obviously rushing science things, and haven't come close to getting a single great scientist. My experience is I would have about half of the great scientists so far in the game. This was immortal/emporer difficulty.
