Although I don't have the computer or art skills needed to make a functioning mood, I nevertheless enjoy brainstorming ideas for fun. Sometimes, I post the ideas that I brainstorm so that others can pick out parts that they might find useful.
This is a rough sketch of a concept for GDI's tech tree.
The details of the idea are explained here: Moddb.com
A couple of questions about this tech tree:
1: I see no Barracks anywhere in the setup, just the armory. Why is that?
2: That building next to the War Factory, what is it? I know it originally comes from a campaign Tiberium-related structure, but what is its purpose here?
3: The GDI Research Lab campaign structure at the bottom, what's its purpose too? I'm assuming that it, along with the above-mentioned structure, are part of some "diverging tech path" setup, am I correct?
4: Lastly, it appears that you can only get the Command Post (probably Radar) from the War Factory, and vise versa with the Airfield with the Tib-related structure. Can you only go down one path, or can you build both paths (up until the last row of tech structures, that is)?
Ah, just having read your blog post on this topic, I retract my questions. Carry on!
Actually, it occurs to me that I didn't adequately explain certain things, like why I used the Armory's image for the Barracks or what the Command Post is supposed to do.
For the Armory, part of it is that I just like the design, but part of it is that GDI would have access to something like the Wiesel AWC [link: En.wikipedia.org ] from there, in addition to infantry.
As for the Command Post, the idea is that it unlocks certain units and provides support powers (e.g., Air Strikes, repair drones, etc.) to make up for the player going down the wrong technology branch to get airplanes.
I also did not provide a link to the correct blog post, which may be useful later: Moddb.com
