Darkstryder completely passed me by... I'd moved onto d&d by 2nd edition WEG SW. Could you elaborate on what that was and how it worked please?
A short preamble, if I may:
There´re three kinds of campaigns: Freedom (sandbox, like Red Tide), Faux Freedom (like Kingmaker) and Pathed (like Serpent Skull).
Darksyder falls into the faux freedom categorie, as it is mapped out, but gives the illusion of freedom of choice. It also works with each player running a number of characters on different levels, where only higher levels count.
So, you´re running an entiry ship and crew, with "high" level characters acting as command staff, "medium" level characters acting as warriors and "lower" level characters acting as support. Most of the time, you won´t be sending "high" level characters into lethal actions, so they should stay the course of the campaign, whereas "mid" and "low" level characters are sent into the direct action and their death would not impact the story, but their survival has some merrits, as they have contacts, connections, and so on.
Translated to a AToW campaign, this´d mean I hand you 1 Commander, 1 L/R jockey, 2 mechwarriors and 3-5 Support staff to run as your part of the crew, inclusing all their special perks and flaws. The goal is to get those commanders along the story line, whilst being able to replace the rest of the staff, whilst the staff survival gives boni.
To make this a bit clearer, take an "low" level technician with an Circinian background. He´s a former pirate and slaver (dark secret) and as long as he survives, you can use his background knowledge with other pirate bands that come up. You, as controlling player, must weight the Dark Secret against possible insider information gained in encounters. The same would hold true to a WoB-trained and enhanced Mechwarrior, wo is secretly a Manei Domini. That character has tremendous inside knowledge, can be blackmailed, sometime has problems with upcoming enemies but has some "specials" to keep her around. Juggle and judge that, that´s the gaming issue here.
