Euphrat & Tigris
is the PC version of the eponymous board game with a tactical and complex rule set. It is set during the time of the ancient Greek civilization where four dynasties fight for supremacy. The basic rules: At the start of the game every player owns tokens in four colours which represent kings, priests, farmers and merchants and a temple. The player can use his tokens to build kingdoms and when one is finished and he puts another token besides it he gets points. The catch is that the points are calculated for every colour separately - and in the end only the player's weakest colour counts.
The obvious advantages of this version compared to the board game are a automated calculation and KI opponents. It also features an improved graphical presentation of the tokens and a tutorial for new players.
