I've been using X-Wing Miniatures for a Star Wars "Edge of the Empire" RPG campaign, originally just for abstract markers for space combat ... but more recently I've been experimenting with a sort of "hybrid" where we use X-Wing Miniatures rules for the space combat, "converting" the PCs' Edge of Empire skills and talents over in the form of modified stats or "special abilities."
So far, the players seem to enjoy it, but I definitely have room for improvement.
Anyway, for RPG purposes, this means that I find I need a lot more in the way of "generic" starships such as Y-Wings and Headhunters ("Edge of Empire" doesn't even have stats for X-Wings, B-Wings, A-Wings, etc.), but also I have scenarios that call for freighters to escort or attack, and so forth. So, I've been digging through some of my other Star Wars and sci-fi toys (and even just some random junk) to see if anything can be put to good use with this scale.
I've tried digging through my collections of Micro Machines and Star Wars Starship Battles. Micro Machines doesn't really have a uniform "scale" as such, since X-Wings, Corellian Corvettes, escape pods, Star Destroyers, and even the DEATH STAR end up being comparable in size. However, with that much variance, maybe I'll just get LUCKY and get something that's close enough for horseshoes, hand-grenades, and RPGs.
First up, the obvious comparison seemed to be for X-Wings (even if I have no reason to use them until I get my hands on "Age of Rebellion"):
The size isn't really all that far off, but of course Micro Machines don't nearly approach the beauty of FFG's models. The Micro Machines models look squat, and the wing guns ridiculously chunky by comparison; however, I've considered using some of the "wings-closed" X-Wings as some sort of "Headhunter variant" for encounters with space pirates and such.
The Micro Machines X-Wings were (and still are) a lot easier to get in quantity than most other starfighters (including TIE fighters), since they come in "open-wing," "closed-wing" and "battle damaged" variants, and there is at least one pack ("XIII," I think) where you'd get nothing BUT X-Wings.
Micro Machines TIE fighters look pretty sad compared to FFG's models. Although the cockpit of the Micro Machines TIE fighter is about right, the wings are way too small, and they're invariably warped compared to the nice, crisp, thin, and STRAIGHT wings of the FFG TIE fighter. My only consideration here is that the Micro Machines might serve as a starting point for kit-bashing "TIE variants" (the cockpit being useful), or making "space wreckage" terrain/decoration.
With Y-Wings, the Micro Machines are noticeably smaller than the FFG Y-Wing, but they're still close enough that I figure I'll give them a try to bulk up my "space pirate" forces, after I "dirty" the Micro Machines a bit with some acrylic grey paint and further detailing.
With the A-Wings, I have the opposite problem, in that the Micro Machines A-Wings are noticeably too large compared to the FFG model. Still, I find myself wondering about the "canon" size for A-Wings: That is a HUGE cockpit: The A-Wing is supposed to be a one-seater, yet its canopy is larger than the two-seater-and-turret canopy of the Y-Wing. Somehow, I had the idea that an A-Wing was supposed to be tiny compared to the other fighters -- something like what you'd have if you took the cockpit "wedge" from a Y-Wing and strapped some boosters on the back and a couple of guns on the sides.
Not pictured, but the Star Wars Starship Battles version of the A-Wing is actually a bit SMALLER than the FFG A-Wing.
For atmospheric scenarios, I've found that the Micro Machines Twin Pod Cloud Car (lower left), while not strictly following canon measurement in scale, still looks *plausible* (at least in my inexpert opinion) next to the FFG YT-1300 and X-Wing.
