It seems like MANY wonders give you "you can choose any Legal civic" or the like. This seems to be not only overpowered but it also takes a lot of fun away from the game as there is less "I can't wait until I get 'x' tech so I can finally adopt Bureaucracy!". Maybe make it so these wonders only open up a single new civic (i.e. the Sphinx opens up Bureaucracy early or the Parthenon gives you access to Representation or whatever). Might be an interesting way to let the player prioritize more. It also seems like (maybe!) wonders are a bit cheap too....I seem to have loads of them. Then again this is my very first pay-through, I'm only on Noble (since this is, essentially, a new game) and I'm on Turn 163.....so don't take my word to heart.
