Old Glory has a fair-sized range of 15mm scifi figures sold through their Blue Moon line, most of which have been around for almost a decade now. They're well-made, have a lot of sculpt variants per pack (generally ten out of ten unique poses, sometimes less), and are remarkably inexpensive if you're an Old Glory Army member. Despite that, I don't see very many painted images of them online. So I've gone digging through my old image files and dragged out some examples for a photo gallery post. You'll have to excuse the wretched quality of some of the images, but they date back to 2011 in some cases and not exactly up to current standards.
You can see the Old Glory web store listings here:
Mix of Universalist Command (who are definitely not 15mm Eldar), Robot Legionnaires, Robot Legion Skirmishers, and Robot Legion Striders
Ten sculpts of Universalists
Only one of the Robot Legionnaires
And I think three of the Velon Skirmishers
Five sculpts of the Nevis
Five sculpts of Averums
Ten sculpts of Betelguesans, who make pretty good pulp Martians in green skin tones, or Star Trek Andorians with blue
Ten poses of Nova Patrol, who are also rather pulp scifi styled
Another mixed Universalist & Robot lot
Wraithguard? What Wraithguard?
War Walker or Wraithlord Dreadnought, you decide.
Six poses of Zennox - one of the few packs that only has six figures
The Nevi make nice stablemates for the Zennox when you paint them in a similar color scheme
Ten poses of Aquans, who also make good Star Wars Rodians if you paint them green-skinned
Six sculpts for the Twanax, which are the other six-figure pack and much bigger than man-sized
Back to the Averums again, only five sculpts but you get two of each
Orion Republic power armor, ten sculpts that make fine Space Marine proxies
Ten different Mercantile Bond soldiers
Ten sculpts of Vletan Reavers
Ten variants of the Post Human Command sculpts, very nice generic scifi troopers
Ten Terran Confederation trooper sculpts, who also make decent Eldar aspect warrior types
What, more Universalists?
Fereen with Orbs, I believ there are only five infantry sculpts but the two drones also come in the pack, making a total of twelve figures despite what the store page claims
More Fereen, this time two sculpts mounted on huge Goranax, these are single-piece castings on 1" washers in the photo
There are a fair number of codes I don't have passable photos for. Maybe I'll get around to fixing that some day.
