Really ought to get back to it. I have a reasonably cool idea for the HK's pose, as well as other beasties from D3 (I figure the last game would lend itself better to collectibles than the originals, even though I prefer the oldies myself). One of these days I'll mess around with the sculpt again, see if I should either continue it and make a mold or restart in Sculpey.
But I'd definitely be up for more Doom attention. It's my all-time favorite game, not even kidding. I'd go nuts for figures, statues, or anything else I could snag as long as it's non-movie.
I'm even working on a couple mods for a port called ZDoom, one of which is Aliens- and Predator-themed (https://forum.zdoom.org/viewtopic.php?f=19&t=29242). Some of you may have heard of the "Aliens TC" back in '96. This is basically a similar concept updated and prettified with new engine capabilities and fresh sprites for the 21st century.
