I have a mod idea in stock. It's name is Command and Conquer Generals: the Ultimate Devastation. It is a TCM which adds a lot of units. It's basically a hybrid of Contra and Rise of the Reds, with lots of new ideas thrown in.

USA- A faction generally good at drones, airforce, and experimental technology.
Leader: Elizabeth Sanger
Manpower: 2.74 Million
China- A faction that uses lots of hordes, electronic warfare, and heavy damage weapons.
Leader: Fu Guan Chao
Manpower: 8.52 Million
GLA- A faction that is good with guerilla warfare and stealth.
Leader: Shah Khalidah
Manpower: Unknown(estimated to be 6.7 Million)
Russia- A faction that uses a lot of brute force and raw firepower.
Leader: Yuri Zworykin
Manpower: 5.88 Million
EU- A faction that focuses on experimental technology, mechanized assaults, and defenses.
Leader: Fernando Sagrada
Manpower: 2.91 Million
PPA- A faction that is highly mobile and very good at nanotechnology.
Leader: Keiko Masahoru
Manpower: 1.63 Million

No vanilla factions though.... 3 generals each, making 18 generals all in all.
(Note: you can change the name of the leaders if you like.)

I also have a few ideas in stock.

I kinda feel like some of the subfactions are off-character or overlapping with each other here.

USA - pretty much what it was in ZH
Mecha Warfare - so walkers, exosuits, right? Does the EU already do this?
Experimental Warfare - Lasers? Plasma tech? Solar tech?
Rapid Deploy - Interesting one. A Rushing USA would be a nice change of pace.

China - Pretty much like in ZH
Red Army - Cannon Fodder General? Either that, or we have a "Highly trained troops general."
Special Weapons - do you mean fire?
Electronic - Off-character. But would be interesting.

GLA - same old
Covert Ops - Stealth General.
Assault - Vague. And off-character. It doesn't fit the description you have for the GLA.
Chem Warfare - Toxin General.

Russia - sounds like China, I'm p-sure there's lots of other things to describe the faction.
Mass Production - Again, Cannon Fodder General?
Electromagnet - EMP General? Hm.
WMD - Russian SW General/Turtle General? Or the "I only have weapons that hurt" General?

EU - P-much RoTR EU. But it overlaps so much with USA.
Adv Tech - VERY Vague. What does constitute as Advanced Tech, hm?
Def Ops - Okay, we got a legit Turtle General here.
Mecha Assault - how does it differentiate from Mecha Warfare?

PPA - New Ideas. Sorta.
Nanotech - Self-repairing/healing troops? Nano chest-bursters? Hm.
Macrotech - do you mean, Mecha? If so, we have three factions witb relatively the same theme.
Special Assault - HYPER Vague. What can be offered here will be a surprise.

Also total conversions mean that you don't use assets from the original game or modified it enough to differentiate it from the original game.

So uh. Its a lot of work. Maybe if you can get a dedicated modding team assembled.

Let me elaborate:
USA - pretty much what it was in ZH
Mecha Warfare - Drones and mecha.
Experimental Warfare - Yes, and Anti-matter and Space tech!
Rapid Deploy - Yes, but more like Orbital-drop dudes, lighter vehicles and armor, but more choppers and aircraft.

China - Pretty much like in ZH
Red Army - Both.
Special Weapons - Yes, nukes and fuel-air bombs.
Electronic - ECM, hackers, propaganda, and stuff.

GLA - same old
Covert Ops - Yes, with a little bit more new stuff.
Assault - Demo + Contra Assault.
Chem Warfare - Toxin General.

Russia - sounds like China, I'm p-sure there's lots of other things to describe the faction.
Mass Production - Yes. But focuses more on vehicles rather than infantry.
Electromagnet - EMP/Tesla/Railgun......
WMD - Russian SW General.

EU - P-much RoTR EU. But it overlaps so much with USA. Pretty much Allies in Red Alert 'verse.
Adv Tech -Battlefield prototypes, plus solar, prism, bit of drones....
Def Ops - Build defenses.............
Mecha Assault - Not mecha. More like combined arms.

PPA - Very much like Empire from RA 'verse.
Nanotech - Yes, using smaller drones, transformers, Nanoswarm.
Macrotech - Yes, but different style.
Special Assault - Psionic, crystal, pretty much like Protoss tech.

And, all existing factions get to have a totally new command center.

Cool

Well, we're posting ideas here for mods. We are bound to have a team assembled. Got some good modders?
