Prior to the changes to mounted units, it obviously was not critical to have iron early in the game. Now I find it quite difficult to take cities without Swords/Longswords/Catapault/Trebs and all too often find myself without a source of iron that is reasonable to reach. On lower levels I can make do but I've been trying to play Immortal lately and if I can't successfully wage an early war I end up waaaaay too far behind to catch up (Science, Cash, Soldier, basically everything). Even with a great start I find myself having to throw in the towel. Yeah, some people play until the bitter end but that is not me! How do others deal with having 0 iron around? It stings getting 60+ turns in the game only to find out you don't have a very crucial resource.
