Just checking, if you choose a stream in Square Bashing how long is it?
In most rules they are from one table edge to another, edge, but in Square Bashing it does not say, so you could argue they are 12"/2 squares like any other terrain piece.
can't say they get used much, and I would tend towards the latter, and assume like in the WOR rules the template only shows the wide/significant length only.
That is a very interesting question. I have played a Walter Schnaffs game recently which featured a river crossing the whole battlefield as this was a published scenario. I see no reason not to have a stream or river crossing the battlefield. A number of actions in the Great Retreat of 1914 featured try ing to hold up the enemy at bridge crossings, both canals and rivers. Similar actions took place in East Prussia following the Russian invasion.
