Wargaming usely consists of spending MOST of your time building,
painting minitures before having hour long sessions of games, using
them. This usely take sup alot of time and you can find yourself
indoors in a compact room for quite a while. To other people this
makes you look like you don't want to go outside and talk to others
and "socialize". That's why people see Wargamers as Anti-social.
But don't let it bother you, as Wargaming can rightfully be called
a 'Hobby' and it's how you choose to spend your time. I'm a
wargamer myself.
