Here's the problem we have. Currently we are not on any specific path. We seem to just bounce around tech wise to whatever we feel is good at the time. This IME is a game ender. Our best bet is to step back and look at our civ, traits, techs, opponents, and what we've done so far. And so far, we've done nothing, but bounce around.
In order to play a successful game we need to decide on specific goals. If we want a religion, the Oracle, army, whatever, we needed to decide on that and focus our attention in that direction. Deciding part way in to switch so we can get this or that will only lessen our chances of success on this game.
IMO Iron Working isn't worth it. The only reason we'd go for it is for iron and if we don't have it we've just wasted our time. IMO our best bet is AH with a straight shot to Alphabet (possible small stray for Pottery) and than trade for all other techs, including the Oracle techs. If we get to Alpha quick enough we can trade for the Oracle techs and complete it.
If we wanted an early religion we should have aimed for it at the beginning of the game.
If we want the Oracle ASAP we end up shooting ourselves in the foot due to a lack of advanced troops to protect us if we research towards it.
