Based on the electronic board game from forever ago, but tweaked into a single player game.
If you wait at the title screen there are descriptions of the items and tiles.
Hints and Tips:
*) stuff happens more often in henges and less often in plains - use that to your advantage. You can't buy more than 2x your warriors in food until you find a beast.
*) If you run out of food your warriors die off.
*) Stay near towns
*) Buy lots of warriors
