I think you should be allowed to change the wonders you choose *before* you work on it the first time but after you set down the buildsite. I've built a Notre Dame but I think a Coloseum would be better for my play style, and it's kind of frustrating not being able to change it when I haven't even invested anything into it's being built at all. Like putting down the buildsite costs nothing, I understand not being able to change it after the first time working on it but I think it would help immensely and allow more freedom if you were allowed to change wonders only when the buildsite has been set down. I hope you all agree, and the devs implement this, thanks.
