Beschreibung
Casus Belli is a game of exploration, settlement, and warfare in space for 1-4 players.

Over a thousand years ago, humanity spread to the stars, creating a massive empire. This empire grew too big and split into four main factions, which then led to a period of war. Conflict led to an era of darkness for humanity. Now after many years, the four factions have started to expand their areas of control again. Who knows whether this will lead to a new war as they expand into an area of space previously forgotten. Some of the worlds are already inhabited by humans, left to their own devices since the last war. They prize their independence, although they may be enticed into alliances. How each faction acts in this new area of space is determined by their prevailing ideology.

Each faction will explore and colonize the systems in the region. In doing so, they will come across ancient alien technologies. However, some of these technologies will lead to corruption. The game starts in a period of peace. Some actions may lead to an increase in tension, which in turn may lead to war. While peace reigns, factions cannot fight each other...unless they have a casus belli. Once war breaks out, the factions will divide into alliances and major battles can occur.

The game plays over ten rounds, and at game's end, each faction scores differently for assets they have on the board.
