I have to say that I like the update. As a fully expanded player myself, I was in need of something new. The graphics and the themes are great. I have just unlocked my second region and can't wait to unlock the third one. The aditional storage is also a big motivation to continuing work on them.
However, as the regions don't give us anything in return (taxes), I was wondering what's the point of continuing work on them after unlocking the 3 regions.
So, please add the regional population to the capital city population count. We spend thousands of simoleons in regions, so it would be fair if those regions could give taxes (simoleons) in return.
