A miniature wargame usually takes at least a table top to play on or can take up the floor of a large sized room. Simply by the nature of the game, a miniature battle needs space for the movement of figures. A game can be quickly won or can take a whole day or more, depending on the size of the game and the skill of the players. Miniature wargaming is an enjoyable hobby and like any hobby can take time and effort, but the rewards are worth it. Building an army or several armies takes time in preparing, painting and mounting the figures on bases.
Armies can be as small as a couple dozen figures or can be comprised of several thousand.
The biggest advantage of miniature wargaming over other types of wargaming is being able to view the armies facing each other on the field. You don't get this type of perpective playing on a board with cardboard pieces or even when playing a computer wargame. It makes the war gaming experience more enjoyable and satisfying.
