To get a local scene started for your favourite wargame, you just have to find at least one other player to start playing against you at your local club or store. You’ll become the founders, the centre of a snowball that will hopefully become bigger and bigger. Other people will see you playing, and might come over to ask what you’re playing.
If the game has been around for a while, you might also get people coming up to you and saying they have models but had no idea that anyone played at your club/store (that seems to happen a lot with Firestorm Armada!).
But how do you get a group started as the foundation of a healthy local player base?
