Okay, time for another example from me:
TNE campaign...
Mueller/shenk system has same size pop (8) as Solee, same Tech level (9), same starport (C). Non-aligned, Impersonal Bureaux govt., way too heavy handed in law level..economically imploding. Had recovered to TL-11 shortly after Virus (1165, now retrograding back. Govt. just tightens its fist and purse strings. Looks bad.
Solee is making overtures, political, economic, military exchanges, etc...
IMTU, Mueller actually fought the Solomani until defeated (planet has mixed Ukrainian-German ethnicity). Then their Colonial TL-11 ships got their Jump drives pulled, stowed at Dunas (a Hi pop world, J-1 rimwards that caved into the Sollies).
So in mid 1202, the Foreign Minister goes with his family (wife, 16 yr old daughter, 12 year old son) to the RC to see what kinda deal they'll offer, right?
Trouble is, SOlee's #1 Spy- Baron AMaraan Abas, finds out, and leaks it to the Guild...who set up their own deal to wax the FM. The FM & Family park their ship at Nike-Nimbus, travel on cleared transport to Aubaine for secret meetings.
FM returns with family to ship, and as they're headed for the J point, get jumped by 3 armed freighters, and shot the heck up.
--ENTER the PC's with one ship (Gazelle CE) just out testing that annual mtce on the drives (paid in Blood sweat & tears, and hard credits from salvage). They answer the SOS, (ala Beowulf), and drive off one (actually they were leaving at that point when # 2 got it), blow up a second, and overhaul & board the third. THe skipper, uses the ship's subcraft to save the civvies & remaining crew on the Muelleran ship.
AMbassador is KIA, but they save his wife, daughter and son! They get to escort him back in flag draped coffin and "Show the Flag". (points for RC). One of the PCs from the ship's boat makes a good impression on the widow.
One month later, the widow is leading the Passive-resistance revolt that overthrowss the government, and a new one gets elected (ala Yeltsin & the tank in 92).
She's now the Prime Minister elect (1 year interim term).
late 1203, one year later, referendum comes up again, Pro RC vs Pro Solee election.
The PC she was sweet on has died (Saved his friends, rammed a Vampire ship with the Gazelle), His best friend has to bring that news to her, besides lead a TF to "Show the Flag". Solee has a flotilla in port as well (doing the same).
Solee starts playing dirty pool, alleges they're sleeping together.(The RC CPT, & The PM). The election goes down, narrowly for RC. This includes becoming an associate member of the RCSA.
SOlee kicks in plan B-counter coup!
CPT-PC saves the day, has his men drop chute in and seize the planetary Meson battery & PAD CCP until loyal units can be identified.
SIS (Soleean version of SolSec) attempts to kill off key Military & govt. personnel (Those not in the coup d'etat get waxed -50% of em. PM gets saved by a handful of PCs, and a man in a Black Trenchoat (TL-14 Ballistic weave)

!
Solee's coup fails. Order is restored, Soleean vessels, miliatry and merchant get stopped from leaving (small space battle).
Soleean Ambassador ejected. Mueller declares war. PM then does really fall for the CPT--hard. But its a restrained thing.. she's the leader of her nation/planet, and cannot be seen in the conservative culture as being a "loose" woman. As Mueller's ally, the RC sends word back of this aggression--but the war has already begun elsewheres.
I ran this romantic angle between the RC Player and the PM of this world, now thrust into a pivotal role (They had some "obsolescent TL-11 ships", 7 major ones, and 21 smaller ones, something Solee wanted on their side..

)in the RC's first war vs a human run PE.
He did write letters from the front to her. Did some of that back and forth. When the war ended he was torn between serving the RC which was screwing him over an operation conducted in the war without consulting the RCN High Command (dereliction of orders--it helped shorten the war, but wasn't what he'd been ordered to do.), or serving the planet of Mueller.
