Oracle. It's a gamebreaking wonder. In every game you can do it without the mids or the great library. But in some games the Oracle is the difference between victory and defeat. Check Mads fickle Isabella for more details.
btw AW is a great wonder, but is very situational.
The Fickle Isabella game is not a game to be measuring anything by. It's an RPC where you have to get all the shrines an continuously change religions whenever you first get a new one!
Mad's RPCs are awesome ways to explore different economies/strategies and have fun, but in no way should you measure whether or not a wonder will make/break a [normal] game by an RPC. Oracle is in no way a game maker/breaker unless you're playing a duel pangaea map and you Oracle HBR or something.
EDIT: In fact, I hardly ever go for the Oracle and I have no problem winning my games. Even in games that I lose on the level I'm breaking into, the Oracle isn't a factor in my loss. I lose in the industrial era or later (never earlier) and I'm usually doing a good job until the late renaissance era.
