For the purposes of this thread, I'm not sure if Lego is any cheaper than WH40k...
(It turns out offbrand Lego is. See below)
Anyway, here's my prospective 1000 Sons "all from one Leviathan box" list. I'll add points values when they come out, to see what it clocks in at:
1 Daemon Prince 210pts
(From Terminator Captain)
1 Terminator Sorcerer 105pts
(From Terminator Librarian)
1 Exalted Sorcerer 90pts
(From Apothecary and a twig staff)
1 Tzaangor Shaman 60pts
(From big neurogaunt, a pokerchip and a twig staff)
1 other character, maybe Infernal Master 75pts
(From Marine Lieutenant and a twig)
2x5 Rubric Marines w/Warp Flamers + Soulreaper 190pts
(From Infernus Marines and toothpicks)
5x Rubric Marines w/Boltguns + Soulreaper 95pts
(From Vet Marines and toothpicks)
5x Scarab Terminators w/Soulreaper + Hellfyre miss 205pts
(From Terminators and under-claw fist-kopeshes and kebab sticks for the missiles)
20x Tzaangor 130pt
(From Termagants and putty beaks and a claw blade)
6-10 Tzaangor Englightened? Or maybe just more normal gors? Or maybe some blue horrors for some infiltrators? 90pts
(From neurogaunts and poker chips and toothpick spears/
bows, or just blobify for horrors, rippers for crimsons)
3x Mutalith Vortex Beasts 435pts
(From sprue pieces, putty, random stuff, spare claws, even bodies/ heads, and costume jewellery/ earrings/ keychains. As well. Rippers in the blob? Free, random pieces models)
1 Hellbrute w/ twin Lascannon and Missile Launcher 145pts
(From Dreadnought and spare head, or a neurotyrant's
thingies)
1 Forgefiend w/ 3x Ectoplasm cannons 135pts
(From the Carnifex and Psychophage smoke stacks)
1 Defiler w/ Reaper Autocannon, Cannon and Scourge 200pts
(From Psychophage, more claws and scratch weapons.
There is a cannon in the set, as a basing piece. And another
Neuro-thingy)
3x2 Chaos Spawn 195pts
(from random bits and melty-twisted sprue pieces and builder's putty.
Neurotyrant's tentacles?)
Exalted Flamer 70pts
(From big Barbgaunt, they're kinda good. I might run 2-3 solo some battles. They're like tactical flying rocket bikes or really split up devastator squads, with deepstrike)
3x Flamers 65pts
(From Barbgaunts, just stand up and melt/bend arms+head)
An undetermined amount of Screamers, to fill to 500pt. 180pts
(From sprue pieces, gaunt claws, drink swizzlers and putty)
Maybe a Lord of Change 230pts
(From Winged Hive Tyrant, putty, a twig and costume jewellery. Maybe use a cocktail swizzler for the staff?)
Umm, that's 2725 points! So you'd actually have to drop squads and characters to make an army. Which gives you plenty of options and playstyles, which is pretty good for a starter box 😁
Still have 4? neurogaunts, 2? ripper swarms, a psychotyrant and his blobs?, and 3 leapers leftover, probably just for bits and claws and tentacles and stuff. Or more Tzaangors or some Horrors. Could conceivably stick the psychotyrant to a kid's robot toy and call it a war dog or a knight if I wanted to. All the leftovers should help model the rest up as a bits box though. Seems like a pretty reasonable project army, that might even go ok on the tabletop. Pity every imperial can now get anti-psyker 4+ on a unit with the inquisition stuff they just released...
Not sure if toothpicks or earbud cleaners would make better assault cannons, but I'll get some extras of both for around the house, and the cocktail swizzles and kebab sticks, and costume jewellery/ charm bracelet trinkets for extra WH40k stuff, at a dollar store. Probably a tube or two of really crappy builder's putty as well, because I don't want to use the decent stuff I have on models that are just blobs with spikes or claws. A $20-30Aussie conversion cost or so? For a whole army 😎
(For anything made from "way too much builder's putty over melted sprue pieces", just lather some $2 superglue on and dip it in baking soda or sprinkle some on. A surprisingly hard yet flexible "stuff doesn't fall off or crack or shrink" coating. Builder's putty too expensive? Buy kid's plasticine/ play dough/ anything. It'll probably hold for a few years with a covering of superglue and baking soda, especially with a coat of paint on it. It's texturing Jim, but not as we know it...)
....
Spray the whole lot blue, shade wash it, add gold bits "all over the f'ing place", chuck some silver or black/really-dark-grey on where it looks too organic and should be armoured or metal or just "bits", or mid-brown for the gors, shade wash that, drushbush it all (possibly just some/all in light metallic blue or green for laziness and "magic" and *every error-splatter is totally intentional, it's for "effect"*, or 7/8ths thinned white/black or blue if you do armour edging), and add a few details. Done!
(Might be worth grabbing a couple of "the cheapest" nail polishes at the dollar store, for detail stuff or metallics. They may even have some "GW quality" paints/ spraycans for cheap too! May or may not melt your miniatures a bit. Not a problem, happy little mistakes are Tzeentch's way of saying "thank god they're not going to unbreak some of the stuff on this list for over a year, exactly as intended")
