That is true. Another problem was our civ, we chose a civ with a bad UU for this, a knight replacement would have been propably better, or cav replacement.
We could start discussing for the rematch.
I suggest we choose a civ with a knight/cav UU, that's a much better timing for a UU than a sword replacement, in a 3CC you won't get enough of GS's or whatever before it's really too late to use them effectively.
In that case the civ would be one of these (please note if I forget someone):
Knight-replacement:
Japan
China
India
Cav replacement:
Russia
Ottomans
