Mainly because you get the oxygen and the minerals in one package. You crack that stuff open, get oxygen out of it and valuable resources in - more or less - one go, other rocks mean you get oxygen - so it's really more of an efficiency thing (a bit like the resources in vanilla Civ4 - a lot of stuff is found everywhere in certain amounts, but the resources represent particular large and pure/useful deposits). Problem, of course, would be that after the first couple of months/years, the resource would become much less important, as oxygen supply will improve and better mines will give you better ore deposits anyway. But Health resources are a hard thing to do... I wonder whether you can eat glowmites!How can you justify this giving health, energy, recycling opportunities or anything else that could increase base size though? Planet's atmosphere already has oxygen (though not enough for humans), and AFAIK there's oxygen in all rocks.

*shrug* my problem with that would only be: That's actually very similar to a process through which black holes radiate/lose energy: it's Hawking radiation.Err I don't remember. That change dates from years back, in SMAniaC. I guess I thought harvesting quantum power was too much of a fluff idea. But as you say Antimatter probably isn't any better. I guess that vacuum polarization idea I just invented doesn't make much sense?![]()
EDIT: Note that all that stuff is actually fine with me as it is now - as a physics student I learned a long time ago stop over-thinking Sci-Fi. Though I have to say SMAC always held up pretty well to the whole over-thinking (at least compared to most other sci-fi stuff), because they kept many things rather abstract.
