One of the great things about miniature wargaming is the vast range of factual & fantasy periods available to play and buy models for.  Here are some factual period examples ...

So, if you have an interest in a certain time period or fantasy, your sure to be able to find figures to recreate a wargame scenario!  Simply ask the senior members (or even some of the more knowledgeable juniors!) where to get these figures & rules and you can start to build up your own collections.  Enjoy the history of that period, enjoy painting the models and, best of all, enjoy playing the battles!
