OnlyLifted: We have to remember, it's only a game. And now you get to try out different things that you learned from your other game. No telling how fast you will be able to progress. Share your # and now you can receive gifts. That's such a great feature that Booyah added that I didn't have when I first started a few months ago.

Just a thought about buying multiple Wonders (e.g. Eiffel Tower or Stock Exchange, or whatever)
It depends on what one wants to focus on while playing the game. The space is so limited, with the exception of buying a whole lot of high rise condos for the steady supply of coins, I've resisted buying many multiples of other items because part of my amusement is making mine look like a little town. I try, anyway.
I suggest visiting other towns and looking at their composition. If you don't mind looking at rows and rows of the same item, then go for it.

My progress is definitely slower with having to save up dollars and coins, but I like looking at the little characters and moving things around in my town.
