I've tried explaining this to my wife: Dwarves ---> Awesomeness.
I love Battletech and tactics games. I recently gave FoG a shot and decided that I'm not a large army painter. Each mini is a work of art and love, and you can't do that with mass army games. So my feet are planted firmly now on getting Reaper Minis.
I agree with all of this. Battletech is in many aspects a duel, warlord is a skirmish and Warhammer is probably a full on battle, but I really just like smaller more personal fights that your mini's and playstyle have more impact then which army you really play or how massive your swarm is. (Not that you cannot have swarms in BT or Warlord of course.)
Painting is something I don't get to do enough of and am in desperate need of practice and further learning but having a small number of mini's that I think look awesome is a good way to like everything you paint instead of feel overwhelmed by them.
