Extremely Standard: Two cybertronian ships crash on Earth. After X years in stasis lock, the occupants are revived and given alt modes to fit in as Robots in Disguise. From there, they must fight their counterparts to decide the fate of the planet and its resources.
-Praise be to Decepticon: Megatron makes it look easy, but being a cog in the Decepticon war machine isn't a drive in the park. You not only have all these blowhard Autobots trying to shoot you in the name of their moronic morals, but your bosses take a dim view of failure, backtalk, and being in the room when they're mad, and like to vent by ventilating 'mechs. Winning the wars one thing, the real trick is surviving.
-Scrapmetal World: The transformers awaken on an Earth that has already been destroyed by human foolishness. Will they restore it, ravage it further, or give it up as wasted and seek a way off.
-Metal in the Stone Age: You've crashed but avoided stasis lock. Now a virgin planet forms you new battlfield
-TransformerPunk: This planet's lifeforms are advanced for organics, and have begun the process of cyberforming their world. Will they ever get to complete it?

Special Team: Your party of Transformers is linked by more than happenstance, you're a specific grouping of Transformers that shares something
-Combiner: You're all part of a greater whole
-Wreckers: The Autobots Dirty Operations squad
-Mayhem Attack Squad: The Decepticons answer to the Wreckers
-Misfit-bots: A more out-cast-y approach where you spend most of the time away from your side, likely because of unusual alt-modes or powers

Earth Fortress: After 4 million years the civil war is mainly a war of resources. This version focuses on that aspect, by having the players work to gather energon and build their bases and superweapons to defeat the others side. There may be Lava and Carpticons.

Decepticon Empire: Megatron has all but won, with Cybertron in his hands and his generals controlling entire battlefleets and warworlds. Earth is one of the few remaining free worlds. Autobots scramble to find some way to turn the tide.

Super Energon Wars: As normal, but its an SRW Earth, with human mechs entering the fray and confusing the issue.

Brave Police Animated: The remnants of the Dastardly Decepticons wander the galaxy, unleashing mayhem on unsuspecting organic lifeforms. Only the Autobot Brave Police can save those planets without panicking the populace....assuming they don't get attached to the local lifeforms too badly.
