There was a little bit of Warmachine VSF action during the Atlantis campaign - forces from Spain (Menoth) and Imperial Russia (Kador) came to blows in the north-east part of the Lost Continent. It was ushistoryprof who was running the forces, as his kids have Warmachine armies.
I have a bit of a fondness for them, I must admit. Lovely minis. One of my sky-pirates is a Victoria Haley mini... she's not exactly perfect for VSF, but she's got brass goggles, and what else is important?
