Anyway, this is just a small thought I've been having. Feel free to comment on it, it's a free forum
For SRs, I think that say in the case of Iron. At first iron should only appear on hills ect ect, but think about it, iron is one of the most abundant minerals on earth! You just have to know where to look, therefore, I think that there should be a technology you can learn "Mining". With that, all squares producing a shield will produce an extra one, and a fringe benifit is that iron icons will become more and more abundant, like every 1 in 4th hill or mountain will contain a source.
Aluminium is another case. It's the world's most common material, it just needs to be properly refined. But you discover refining BEFORE rocketry, right? That's right Timmy! That is why aluminium shouldn't be THAT rare. I mean, on a game I played on a standard sized map, my empire dominated about 75% of an entire continent, which was equal in size to the other one (only 2 in the world). After discovering rocketry, I nearly crapped myself when I saw I didn't have one source of aluminium Long story short, the Zulus and Japanese got wiped off the face of the earth, but I got my aluminium so it's all good in the end
Lastly, before everyone starts telling me to shut up. Oil should appear costal and ocean squares as well. Alot of the world's oil comes from offshore platforms. With minaturisation, you can expolit those offshore oil sources and for those sources in the middle of the ocean by building a special unit who's sole purpose is to lay down oil rigs. This would add an extra dimension in battles because naval superiority would be cruicial in order to maintain your supply of oil.
Anyway, those are just my suggestions.
