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.
The only thing you have to base these ASSUMPTIONS on is wishful thinking. There is no indication that any of this is remotely true. Perhaps what you have described is the way you would have made the game, but I'm going to bet that you are not on the design team.
It becomes very hard to have any sort of actual, reasonable, intelligent discussion on this site because those of you that are convinced (or have convinced yourselves) that Civ V is going to be the best Civ ever simply tell any and everyone that say anything that even hints at criticism that they are "just wrong". No evidence other than your personal opinions necessary, others are "just wrong". People are allowed to disagree, and are not simply "wrong" because they have doubts that this iteration of Civ will be any good.
My personal opinion is that they are taking all the good things of Civ out and that this Civ V will be a piece of excrement that I will not waste my money on until it is in the $2.99 bin, if then. Disagree if you like, but my opinion, being just that, isn't wrong.
