There's not the same amount of detail. There's no information on trade routes, maintenance costs, happiness, food, ethnic breakdown, great person production %. Of course the sliders and religion stuff is gone, because that's not in the game. I certainly hope there are more options to display some of this information, and that the information itself is not also gone from the game, because that would indeed be disappointing.
The special resources stuff is also gone. I noticed that there's information on strategic resources on the top bar of the main display, but this doesn't tell you what resources are available to this particular city.
I do like how the specialist buildings have clear "slots" that you can assign population to. That's a big improvement over the Civ IV specialist system, which I never liked and is very non-intuitive.
Just because you can't see it doesn't mean its there. boot up civ 4 and tell me you can see your gold or production breakdowns without having to mouse over them. tooltips are a great way of revealing more information when you want it, and not cluttering up the screen when you don't. And it fits perfectly with the amount of minimising going on.
All the builing tabs can be hidden away at a click, the citizen allocation focus (the auto menu to right of the queue in civ 4) can also be clicked away. The queue can be revealed or hidden, the choose production menu is hidden until needed. It would follow suit, would it not that the things that are missing are just hidden.
Trade routes - Under gold breakdown, tooltip.
Maintenance Costs - Gold breakdown
Happiness - You can clearly see the net happiness at the top of the screen in taht little bar.
Ethinic breakdown - Might not be in, but i its hidden its probably a tool tip when mousing over the citizen:11 box.
Great person production - Would slide nicely into culture tooltip.
Food! - Its in that citizen box I just mentioned. And its net food which is nice, so another breakdown will be there, so tahts where health will appear if its in the game.
As for strategic resources, well done for noticing the net resources at the top, it doesn't really need to say if the resources are in the city, the net resources could vanish from the abr if looking at a city not connected. Or hopefully they'll remain and you'll just get a large imposing notice saying the city has no trade route, and no access to resources.
Civ 5 looks simplified to a point of sheer stupidity, till you get out the magnifying glass, and see the intricate network of complicity.
