Oh no I get that, what I'm saying though is the aesthetic similarities down to a specific sculptor or merely working in metal ?
Well, I guess there aren't that many different ways you can do a steam/clockwork golem that looks suitably robust for battle. Also, as with many games from the early 2000s, I think they channeled some of the WoW aesthetics.
The initial Warmachine figures were sculpted by Mike McVey, if I am not mistaken, but I don't know for sure who sculpted the golems for MK - Jeff Wilhelm, maybe, but I cannot confirm it right now. Tim Prow also did some sculpts for the range, IIRC.
