I'm in the process of noodling through some ideas for a Star Wars d6 mini-campaign. This may or may not happen, and as a consequence I won't be putting up any spoilers here for the time being. However, I have a few ideas, so here goes:
Three parts, three sessions each, four acts each: The mini-campaign is expected to be a trilogy of adventures, where each adventure is split into three sessions (though I'm not sure if these should be 'regular' 3-hour sessions or extended 6-hour 'weekend' sessions). And, as is my wont, each session would be split into four acts: introduction, rising action to the midpoint, falling action, denouement.
Three set-pieces: In addition, it's quite noticable that each of the Star Wars films has three big action scenes of varying scope. This ties in very nicely to my 3x3 structure, in that it strongly suggests that each session should be built around one of those action sequences.
On the PCs: four humans, one alien, one droid, one Force-sensitive but zero Jedi. The game is intentionally taking significant influence from "Rogue One" (hence the d6 system), which means focussing very much on the Rebellion, but also avoiding turning it into another episode of the "Jedi soap-opera".
(But that does leave me in a quandary: this all 'feels' like it should have pre-generated characters supplied, but I'm very much of the opinion that campaigns should allow players to create their own characters - pre-gens are best reserved for one-shot games. Which obviously is something of a contradiction. I'll need to think on this some more - a one-shot might be a better idea anyway, or maybe I can start with a char-gen session. But either way, I'm pretty sure on the "no more than one alien, one droid, one Force-sensitive, and no Jedi" thing.)
Seven locations: each of the three parts will make use of three locations, ideally being two planets and one space-based. However, one of the features of a trilogy is that the third part should revisit many of the themes and conflicts introduced in the first part, which means revisiting some of the locations. Consequently, part one would use three distinct locations, part two a further three distinct locations, and then part three would open with one new location but then return to locations visited in part one.
And that's where I am right now. In future posts I may flesh out some more of the details, or I may start presenting the character profiles for the pre-gens. (Though, first, I need to resolve that "one-shot with pre-gens, or campaign with custom characters" question!)
