Why the heck did you get rid of the import/export function? I was trying to pick this game up today on Firefox after giving it up when Chrome stopped supporting Unity, and discovered I can't bring in my old save. Seriously, why?
I've gotta say, I also enjoyed the first one more. It's a little hard to peg exactly why, but I think the first one felt more like you were exploring uncharted waters and delving ever deeper into them, where this one has more of a sectioned off, just-doing-another-level feel to it. That isn't necessarily bad, but it's definitely less interesting to me.
It would be thoroughly amazing to be able to prioritize certain types of buildings. Housing, for example. Getting that Idle Game achievement is going to take foreeeever.
The credits are so bloody long! Agh! I've already seen all these places in the game, do you really have to show me one name at a time with a random screenshot in between?
