Help with parameter data

[phoenix]

Thanks Agmoss. But how do you know this? Where is it I can find the list of impassable terrain types for each unit type, in each different game/scenario? It's not in the parameter data, as far as I can see. As I pointed out above, the PD gives a terrain cost for roads that is the same as water, when clearly one is impassable and the other not. I assume there must be somewhere else that I can find out that 'creeks' for example, are impassable?
