im looking for the real basics, things aobut shields, food, hammers(?), things like that. Dont even realy know what a shield is. thanks
Shields no longer exist. The overwhelming majority of Civ may be reduced to three basic things:
1. Food, which is (mainly) used to feed your citizens and grow your cities;
2. Production, which is used to build almost everything in the game, from banks to city walls to phalanxes to jet fighters to the Pyramids; and
3. Commerce, which is either taxed and converted into Gold (useful for paying maintenance costs) or Research (which is used to acquire new technologies).
Now, each of these items is represented graphically in the game -- if one of your citizens produces a unit of Commerce, it will appear as a little gold coin. If you convert that Commerce into Research, it will turn into a little beaker. Hence, we frequently refer to Research as "beakers," as in, "I need 200 more beakers to develop Optics."
Production is represented in Civ4 as little hammers. Hence, you'll see that a Marines unit costs 200 hammers; that just means that your city needs to produce 200 hammers to build a Marine. The problem arises in that, in all previous versions of Civ, the symbol for production was a little shield. Hence, veteran players frequently refer to "shields" out of habit even thoug the modern term is "hammers." As a newbie, you actually have an advantage in that you don't have to unlearn all the old reflexes.
Did this answer your question?
EDIT: Yes, everyone, I understand that I've glossed over a lot of the details here and there's a lot of Civ that isn't covered by this. You have to feed newbies slowly, or they'll get sick.
