I love this post and created an account just so I could respond, I couldn't agree more that more options are needed, entertainment, store
I was thinking about things about gameplay that I find frustrating also...
With all the "Platinum Key" upgrades....I'd like to see the game add some Platinum Key Museums under the Education tab. In older versions of the game, Museums fell under education....and having the chance for high epic point buildings under the education tab other than just having a bunch of Universities all throughout the city would be nice...the Lourve would fit nicely in Paris, the Gougenheim, with the Empire State building....and so on. This isn't just an Entertainment issue, although I notice that "Zoo" and maybe even "Planetarium" are missing from the Entertainment ideas which I'd also like to see, but....
Also....if you consider what I assume that EA values Platinum keys over Gold Keys...and how many Platinum keys are necessary to purchase the bigger ticket items from the Platinum Key menu, I think the epic point values assigned to those buildings should be either 4, or maybe even 5 epic points. If you have to pay 35 Gold Keys to get the Statue of LIberty for 3 epic points, I just don't see how 50 Platinum Keys for the Sears Tower is also a 3 point epic building.
Just my two cents. I like your ideas as well.
