Civilization 5: Brave New World Message Board  

I'm running into an issue where I get to a certain point in a game, which is dependent on the length, most currently a Marathon length game, and when I get so far into the tech tree, the "1 Turn Research" actually increases research time instead of decreasing. Am I doing something wrong?

I'm having the same issue. The point changes, however, depending on the size of my civ. Larger civs can make it into the Modern era before this becomes a problem whereas smaller civs start to run into the problem around the end of the Renaissance.

the value is so large or added that the value (when read as a signed value by the game) is interpreted as negative value. The problem is that we tried smaller values, which then the game took too long (but still faster than normal) to do research, and etc. so we settled on the value that seems to work best.

best,
Cal

Fair enough. Thanks for responding.
