We've only played a couple of test games in my group, but I was wondering how much terrain regular players put down on the table. It doesn't seem that you require too much to play this game, and certainly not very large pieces at that.

Can anyone give an indication of what works or doesn't work for them?

well, sorry for answering you late, I didn't notice the post.

When I play both for BI / Impetus usually there are 3-4 terrain features, of which one tends to be an impassable terrain as Difficult going is not enough if you want protect an anchored flank. It is mainly usefull if one side have no enough cavalry to protect the flank(s).

I haven't seen so far many usage of BUAs.
