Re: English, French or both?
We played the first scenario - the French won - then we changed sides - the French won again.
We decided to play the same scenario again and again until both of us achieved a victory on the English side (which happened in the fourth and fifth session, I think).
So: no preferences for me or my wife so far.
As we *had to* play or test several other games since then (I sometimes translate game rules and components for a German publisher), Battlelore hasn't come on the table since weeks (though my wife and I really love it - btw. my wife was very sceptical at first when she heard that it is kind of a battle simulation).
