South Florida is currently being dominated by Warmachine and Hordes. Malifaux is essentially non existant, there are a small amount of players but it is not their primary game. Fantasy is in the same situation, but does actually have tournaments at the last Sunday of every month at Tate's Gaming Satellite.
Sunshine Adventure Gaming, the only wargaming store in Miami, has recently dropped official support (meaning will no longer be stocking) for
GW products, and just last week dropped official support for Warmachine and Hordes. Essentially, Sunshine just left the wargaming market, leaving no store in the Miami area that supports wargaming. This means one has to drive to Broward to go to stores that officially support wargaming.
Adventure Game Store, Past Present Future in Davie, FL and soon to be Tate's Gaming Satellite are hosting monthly/bi-monthly Warmachine and Hordes events. We do our coordination primarily using Facebook groups, such as
SFLA Warmahordes.
