I could see it being made just to keep up with the "old man actor" brand of improved head sculpts. Arnie, Harrison Ford, Mark Hamill.. I'm sure I'm missing a couple more off the top of my head. And as for costumes, old man Arnie was about as non-costumed and accessorised a figure as we've seen (and yes, I still like having it in my collection). Hoodie and shotgun. The classic leather jacket look from T1/2 is at least iconic for that Terminator character, so it is a lot more costumish if you like. Take out the weapon and the damaged head, and someone who wasn't in the know would assume it's just old man Arnie going down to the dairy to get a cigar..
