Do I have to pick only a few? Apart from the sex-crazed participants [groupies? Unfortunately no, just weekend flings on the table 
] I’ve enjoyed the painting, building terrain and models as well as playing lots of different kinds of games. The history is what makes this hobby unique among conflict game genres… and don’t forget game design tinkering too. Time is the only restricting factor for doing one over the other. I would hate to think of doing this hobby without one or more of those activities.
