I always use smaller buildings than I should, especially for 15mm games. Realistically I know they are too small but Skirmish battles need few buildings anyways. I figure if I can imagine a tiny piece of lead represents Boba Fett, then I can take some liberties with the buildings. I used to game in 28mm and even thought the buildings were monstrous, they would never really support all the rooms needed like hallways and bathrooms. I actually make separate interiors for my buildings now so this isn’t as much of a problem. I appreciate large buildings, but storing them-no thanks.
