Gaming, and wargaming in particular is a hobby which encourages the collector in one. You have to have a certain amount of discipline to collect, assemble and paint even one army. But this is rarely where it stops. How many gamers do you know have decided on a system, collected and painted their army and said "Right, that's me done!" Of course, with so many systems, eras, scales etc as well as a multitude of miniature and gaming companies on hand, this theoretical gamer would be very rare indeed. Most of us play a few systems and possibly have more than one army for each. But there's another level to this. The infamous lead pile.
Anyhow, if you have no idea what I'm talking about, lucky you. For the rest of us, the next time you stare at your tottering tower of boxes of little lead and plastic fellows waiting their turn on the painting desk, spare a moment to wonder why DO you have so many ?
