Grand Warfare
As it says, this is not a singular versus match, but a war.
Masterminds: Revan
Thrawn
Additional agents: For Revan: Mandalore the Ultimate. The Exile. HK-47. Malak. Exar-Kun.
For Thrawn: Vader. Luke Skywalker (LotF). IG-88. Boba Fett. Starkiller.
While it seems biased with actual named people, the fleets consists of:
Revans: The entire Mandalorian Armada, along with the Republic fleet, as of the Mandalorian wars. He gets a cadre of 200 sith from the Sith Empire, along with the Star Forge.
Thrawns: The entire Imperial Navy and Army as of ROTJ, as well as the Rebel fleet from the Vong era (beginning of the war), along with 200 Sith from the Sith Empire. He gets access to the Eclipse.
Thrawn gets a super weapon, Revan gets an uber factory. All tech is updated to the LotF era standards, so there is no tech advantage. Mandos only have 100 Basilisk war droids unless more are made. Thrawn gets 100 Dark Troopers (all Phase III) unless the Arc Hammer creates more.
Thrawn currently controls the Core, the Deep Core (all hyperspace lanes are safe for travel there) and half of the Mid-Rim. Revan holds the Outer Rim, The Expansionary Region, and half of the Mid-Rim.
Given these resources and people, who comes out on top?
Note- Indigeneous species are assumed to be neutral and can not be swayed. No ewoks.
This takes place 5 years before the Vong invade. If the time when they invade is reached, they come in through Vector Prime.
