In FASA's Circus Imperium, are you allowed to turn your chariot around on an oval track?
One of the tactics suggested during a previous game was for a player who has no chance of winning to turn around and kamikaze the lead player with a head on crash. The logic being, is your loss is worth my death.
There are rules for head on collisions when we have them with the figure-8 track. Would you allow the player to turn around and go the wrong way down the track? Is a full turn penalty enough? Having to start/finish in the inside/outside lane?
