A play of word of blood is thicker than water. Which means families as some of yall have been saying. Personally, I think this kinda of sucks... I prefer strangers playing the game.
Also, is the season in Egypt maybe? My first thought was the Nile being turned into blood from that bible fairytale. Not to mention the music sounded "Egyptipianish".
qwert2 ... I don't think their is any real evidence... and no amount of blood from a battle would be enough to kill all the darned fish haha.
Not to mention... if you follow all the books that could be in the bible AKA some of the Hebrew text that get left out. All the rivers in Egypt were turned to blood. Not sure what battle is gonna do that?
