Idea for the first expansion of SC2

They could add a small amount of terrazine gas (preferably not at the main base) that you should aquire in order to make spectres and other new units. So my point is not just adding more units, but also a third resource that's not as critical as minerals and vespene but still important. I bet that some creative maps could be made with this idea. And the new units would be kind of unique.
I know I'm thinking way ahead of time, but what do you think?

 

I don't want a 3rd resource for multiplayer.

 

I see the concept, the whole "you need to go out there and get this or else you may lose!"

But they did a fairly good job with the uber-mineral patches. Those sort of fill that role.

This could work, if it was a minor thing for some real risk/reward. Like the units it makes are a single unit per race that is also balanced, but still very good. Or those resources can be spent on upgrades for current units that go beyond the typical limit, or research faster when this resource is spent on them.

I just really dont want to see it as something that is necessary, because thats just more and more stuff people are forced into doing that takes away from the actual strategy of the game

 

Except that every single MP map would need to be revised to be compatible with this.

 

For it to not be really necessary; there would have to be units built with stranded mins and gas that counter units built with the third resource. If you can be countered with stranded troops, what's the point in trying to hold onto the third resource? Not to mention, if I see my opponent going after the Tgas, I'll sorta know exactly what he/she intends to build.

Not the worst idea ever posted here, but, I don't see it happening.

 

Terrazine is already an implemented resource in the editor. It may even be in the campaign. I don't think it is used for special units, but there are things you do collect for those. Basically, all of the stuff mentioned is already in the game.
