neat, an /awg/ thread and then I forget to reply...
To end this wall of text, I want to ask about rules. There's supposedly other "ragequit 40k" games out there, as well as a bunch of One Page Rules YouTubers, but I've not found them. I only know Bolt Action, and One Page Rules. As for OPR YouTubers, I only know GoodNuff Gaming and One Page More.
your google-fu is lacking, basically the biggest OPR ad/shill creator is
https://www.youtube.com/@WylochsArmory way back before it was cool. he also does terrain, so should be right up your alley.
as for other ragequit games, xenos rampage is probably the next biggest. stargrave was already mentioned which is the scifi-version of frostgrave, it's skirmish (so you don't need a lot of models or tablespace) with an injection of rpg/narrative since you keep your characters between games. really solid stuff. no scifi oathmark yet, but who knows...
there's even a neat STL package for frostgrave around:
https://www.kickstarter.com/project...city-3d-printable-stl-miniatures-and-terrains
has a follow-up too, and right now there's a whole not!rangers of shadow deep one I didn't know about. this really is the worst part about 3d printing, you constantly come across new great stuff...
there's also some talk around trench crusade, but the community is literally reddit and worse, not sure if you wanna deal with that.
battle for antares is another I always wanna dig into but somehow never find the time, can't say how dead it is now.
if you have someone young in your family and the itch for wargaming, you can grab some of their matchbox cars and use them for gaslands. never played it myself but lot of people seem to like it.
mantic, if you haven't checked them out yet have their own alternatives, they have their own models but in the past they were pretty chill with using others.
since you were asking about narrative play, OPR just released one recently (and there are older ones). there are also some co-op wargames. rangers of shadow deep and 5 leagues/parsecs are probably the biggest. first one is from the same author as frostgrave, more scenario based. 5 leagues/parsecs is less preset and more running your dudes running through a bunch of missions and the "narrative" develops from there. here's a review:
if you need minis, modiphius (who owns it now) actually made some together with titanforge:
https://modiphius.net/blogs/news/five-parsecs-from-the-titan-forge
but all of those are model agnostic, you can use any model and scale you want. some stl creators have their own game, but I never really looked at those.
From what I can tell on the internet, one problem is that a typical 3D printer (FDM) isn't particularly good for minis as 3D prints have obvious layers, so any detail would get lost. Resin printers are expensive and requires the use of toxic chemicals, and is a more involved process, but gives the details you want in a mini. But 3D printing is supposedly improving quickly so maybe that is outdated.
you can do acceptable minis with FDM, however it's gonna take ages (small nozzle, small layers etc.), resin is simple faster and gives you better resolution too.
improving we'll have too see, bamboo pretty much knocked a lot of companies on their ass who were dragging their feet with little progress, now they have to compete with a printer that is pretty much consumer level and not hobbyist anymore. resin hasn't made big jumps yet afaik, although the athena has some nice features (for a price). inevitably those are gonna trickle down to cheaper levels, but at what speed and price I can't say.
as for the resin itself there are some plant based, but since it's a bit more expensive most just buy the usual and less hassle. and you still have to deal with all the waste from supports. inkjet sounds like the best method yet and even does color, but since it's proprietary top to bottom and expensive, it's out of reach for private users.
Something else I also found while looking up those models. Similar to, but legally distinct from, film characters. A bit more expensive at £3-£4 each, but things like "Intercepter Driver" that is clearly Mad Max, "80s action hero" that is Snake Plissken, all you need is the scope for his silenced Mac-10. I don't know what you'd use them for, but fun to see.
ah, found papsikel's models I see. dude's not shy doing literally anything on top of his own stuff. theoretically you can use them wherever you want, especially games where you create your own band of misfits or heroes, like 5 parsecs or frost/stargrave and can stat them. or you just print them to trigger people...
