That being said: Warhammer 40K isn't just a "wargame". It's a *collectible* wargame, where you build your own army and you assemble and paint and modify your miniatures.
Seriously. 40K fans who build full armies are *scary*. We're talking hundreds of dollars and *thousands* of hours of work, here.
It's the geek equivalent of people who restore classic cars by hand.
