As one of my hobbies I put together and paint miniatures for tabletop wargames,
mostly Warhammer 40k and Warmachine. Those are miniatures in the 28mm scale.
I try to play the games that go with the minis
too, but modelling (converting) is what I like most about the hobby.
I've been playing 40k since 2002, starting out in the 3rd edition.
