- no established heroes
- it would be localized
- it would be "small scale": a single Star Destroyer, a single Federation planet, the remote has-as-can Federation fleet
- it would let each side eat their cake and still have it: Trek would have warp speed (rendered mostly pointless by the absence of reason to use it - apart from running), transporters (rendered useless by alloys in the SD hull, shields, or even just ECM), and even the opportunity to examine the culture of the Empire (with a peaceful visit - via shuttle, "the juggernaut is built solely for war: there are no civilians aboard, and while their sensors are quite powerful, they have little to no interest in exploration.") Wars would have the insane firepower, hull and shield durability, and a reason not to just open up a can of whoop-ass right away.
- it would be left "unresolved", with both sides claiming that if their heroes had been on-scene "it would have been different!", yet displaying the disparity.
"Captain, do not test my resolve. Gunner: one turbolaser shot only..."
"Lasers? They can't even penetr...*static*"
