Alright well in some minor discussions with people, here's the ideas that I/we've come up with; I'd appreciate feedback on if people like them, if they're feasible, and how to do them.
Panzer Tanks:
Sorry just kidding.
Roma-centric: The mod will definately be Roma-centric, meant to be played as Rome and Rome alone. There are plenty of mods, such as EB, to give a balanced experience, I want this to more represent a depth to the Roman side of things that cannot be expressed in a more traditional Total War setup.
Rome: I'd like to break Rome up into a bunch of factions based on regional control, with their traditional allegiances and affiliations. The two main factions would be the Populares/Caesarions, and the Republicans(or whatever their Roman name was)/Pompeians. Caesar would have more territories, most notably Gaul and Cisalpine Gaul, but Pompey holds Italy and is on better terms with most of the provinces (especially Spain and Asia). Rome would have factions for Hispania, Africa, Asia Minor, Greece/Macedonia, and Syria/Middle East.
Factions and Shadow Factions: The mod would likely start right before the Civil Wars of Pompey and Caesar; this means most of the traditional Roman Empire is conquered, or more likely, under Roman influence/satellite states. All these states, like Rome itself, was constantly under civil war and threat: Egypt, Numidia, Armenia, Parthia, etc. I'm thinking about the following factions:
Roman:
- Caesar (perhaps destruction can trigger Antony and Octavian armies)
- Pompey (perhaps destruction can trigger Brutus/Cassius, Cato/Scipio, and army of Pompey's sons)
- Spain
- Africa
- Middle-East-
- Asia Minor
- Greece
Other factions:
Germany
Numidia
Egypt (and Shadow Faction)
Thrace
Pannonia
Pontus/Bithynia
Armenia (and Shadow Faction)
Parthia (and Shadow Faction)
Scythia

Overall, I want to achieve something more akin to Alexander TW than a fully fleshed-out TW game. I think this is more realistic for a timely release and a finish, as well as a better experience for something focused like I'm planning. I'm really not prepared to do something on EB/RTR scale or manage a team of that size.
On the other hand, for setting, it can be set in the Triumvirate between Octavian, Antony, and Lepidus, but I haven't thought much about it.
If anyone has good ideas just please post them here, I'm really not so great with RTS design stuff.
