I have always wanted a slower civ, and marathon on civ4 is exactly what I wanted. Marathon is ideal for warmongerers who get fed up with the faster speeds making units outdated before you can get them into battle. A cultural victory is potentially quite tedious waiting for those quarter million quavers to rack up. You can even use Ironclads !! Normal is ideal for those who want to go for cultural type victories. Painful for warmongers who find that their macemen are met by infantry by the time they have walked into battle. What say you all?
