KITBASHING is defiantly more than a few parts added to a kit from another. Usually I would call that PARTS BOX building.
For me KITBASHING is combining components from two or more kits to create something uniquely custom.
Or something unavailable from a manufacturer. But you can call it what ever you like, just build it!
What's so defiant about that model? Or, about kitbashing?
(If you're going to parse words, you have to be consistent and parse all words.)
It's all semantics ... and in the grand scheme of things ... none of it matters much. Call it what you like, kitbashing or parts box building. Just don't call it scratchbuilding.
There used to be a couple of people here (and their fawning posse) who would call what you describe - scratchbuilding. It ignites wars.
But, then, come to think of it, I've never seen a built-up parts box, either.
Speaking of semantic wars, just don't get us started on the kit vs. model argument. I KNOW what is RIGHT, it's just that there's a few fools who don't agree with me!
