The Crossroads of the Aether
Some Swiss live-action roleplayers have long been fans of steampunk, but the first ones to organize a steampunk game in Switzerland were the S.T.I.M. group.
The game featured all kinds of cool props, including iPhone-controlled lightbulbs
and nice atmosphere complete with absinthe bar and class warfare.
I reviewed it in detail in a blog post, also linking to my propmaking articles, including the world famous portable steampunk turntable.
Sounds quite interesting sir, best of luck to you! Cheers!
