It is great fun sitting around a table with friends or family playing a tabletop game. However, when you are out and about, you also want to play games. So you need something that is portable, quick to set up and quite rugged. If you want to play a game in a restaurant, while waiting for food, the game has to be either very quick, or easy to stop at any point. The game also can't take up too much space during play.
A lot of recent game releases have done away with old fashioned, wooden game pieces or cardboard standees and replaced them with miniatures. They are either included as part of the core game, or offered as upgrades - but in most cases these miniatures are highly detailed and add an extra interest to the game, bringing everything to life. These miniatures have attracted new people to tabletop gaming and even created new business for artists who offer to paint miniatures.
If you have bought a number of tabletop games, you will have noticed how some games fill out every inch of space in the box, while other games are basically a large box of air.
