It's tempting to put all this together in 15/18mm in addition to the large 25/28mm collections I have, but I just can't be bothered.
That said, I love Blue Moon's stuff - much of it would be quite useful for what you are after. Note: the buildings are correctly proportioned so seem very large for the game, but I think that's the point. I think some could be ok fpr use with 25s frankly.
