Caledon 194,183,23 – While I do not always find every manifestation labelled “steampunk” appealing, The Independant State of Caledon is well wrth the time spent for a visit. The builds are visually stunning, harmonious, interesting and well-thought out. Don’t miss Ordinal Malaprop’s lighthouse shop, Marconi, Maxim and Tesla Associates, or any of a dozen other places there I haven’t even been yet.
I should add as a postscript that Caledon is actually four adjacent sims.
