Well, Smeagol, you and I have had this conversation before, I think, so you probably can guess were I'm goin', but for the sake of others, I'll be a bit more detailed in my answer..
Forst of all, I'm first & foremost a Military Modeler... This means that I build military models that encompass all the areas of the battlefield, i.e. Land, sea, & air... Although I don't do large Navy Ships of the Line, I do small craft that can be found in 1/35th scale.. Since I build dioramas exclusively, I model vehicles (tracked and wheeled, Combat and support, tube and rocket artillery, motorcycles, male & female figures both military and civilian, horses, donkeys, dogs, boats, aircraft, houses, barns, sheds, shacks, trees, shrubs, fences, walls, roads and trails, to name a few)... Now that that's said, I also build civilian vehicles and aircraft which may be needed in one of my dioramas... That includes military vehicles that have been built up from their civilian counter parts, like staff cars and the odd Citroen here & there.. I also build Sci-fi dioramas, or have in the past, since the [i]Star Wars X-Wings, A-Wings, Snowspeeder, & TIE Fighter, Battlestar Galactica Viper & Raider, and Star Trek's Shuttle crafts & pods... I like to do thaose because I can build whatever support gear and bases that strike my fancy, and I can light 'em up in all kinds of different ways, LED, incandescant, miniature and automotive, AC/DC, steady burn and flashing/chasing, colored & plain...
I use plastic, metal, wood, paper, cloth, epoxy, resin, RTV Rubber, Autobody filler, celluclay, and plaster, and I glue, solder, hammer, nail, and tape stuff together and paint with enamels, acrylics, oils, water colors, tempera, latex, and magic-freakin'-markers ...
So basically, I'm stretched about as far across the hobby as I'm willing to go, and am not going to build a gundam or mecha or any of the "Japanimation" stuff because it doesn't interest me in the least...
You'll have to be content with Galictica Hangar Bay diorama that's in the pipeline, and before you say it, I LIKE "monotone" spacecraft that are heavily weathered, dinged, dented, stained, & scorched...
Bottom line is that I don't want to build any sci-fi kits from any scfi-fi shows or movies that I've never seen, or didn't want to sit through after a few minutes trying... I'll do Star Wars, Star Trek, Alien II, Battelstar Galactica, Lost in Space, Space: 1999, and the like as the mood strikes me and kits are around though...
That, young Jedi, is the extent of what I'll do... No "Panzer IVs in Space" though, no way, no how...
Come up with another idea like your Secret Santa Armor group build though, and I'll play again... That one was a keeper, even though I haven't started my kit yet...
G'luck, Space-case..
