Callisto is a really addictive family game by Reiner Knizia, which can be played over and over again by family members of all ages. It's a game of building empires and preventing others from building theirs! Highly colourful and tactile. Maximum time 15 minutes, visually exciting and strategically challenging-as one expects from the #1 games designer in the world.
