I'm a casual gamer, playing Civ sometimes. After a few Civ 5 sessions I've found Epic speed quite enjoyable, and then tried it with Civ 4. In a new large world on Epic speed I died from barbarians on ~60 turn - a four archer squad captured my both cities when I barely had a warrior there. As far as I know, barbarians start to spawn at 50 turn, regardless of the game speed. If that is correct, how do you deal with them on marathon?
