If I can toss my humble opinion in here...wargamers are the best!
Talk about being able to just have fun, during *all* aspects of the hobby! They love everything--the painting, the converting, the collecting, the backstories, the actual game....
The difference between wargaming and even other kinds of gaming is immense...at the store on a Saturday, we can have two or three tournies going at once, one 40K, one Magic, one Mage Knight...and the 40K players will be having a blast. They're talking, making noises, grinning to beat the band...the Mage Knight players are usually having fun, although they tend to squabble more and the cheese factor is higher. The Magic players, they have fun collecting and talking about the game, but when it comes down to actually playing the game, they're much quieter and more serious than wargamers...they're maybe still having fun, but *I* can't tell...
Anyway, what I'm trying to say is that there is nothing cooler than a bunch of 40K players having a blast together. The vibes are awesome, the players are usually just super.
