So I've been thinking of starting up a region for a Steampunk city, any recommendations for lots and mods?   Obviously cool, old-fashioned trains and trams are called for.  Airship ports would be nice too. Mods that change road and street surfaces to something less modern and more Victorian would be a plus too, as well as ones that would replace the default cars with something more period appropriate.  Some cool coal or gas power plants and industrial buildings with lots of giant gears and exposed pipes would be nice as well.   Of course, real-life Victorian buildings would go well with the setting, along with some older buildings to give my Steampunk metropolis a sense of history.
