Well, I haven't found it so overrated in a SG (D1: Indian payback) I'm in: they are so belliquous that, on Monarch, we are up Middle Ages on the other civilisations. I know it is monarch, but I would expect them to have chivalry when we get to military tradition, which will most likely not be the case.
The only one of them that did actually research some is Germany, which is 2 techs (1 + their freebie) into the MA, while we are heading towards gunpowder (Economics and Navigation are in).
So my question still stands to me ...
