Re: The Action Figure and Toy Collecting and Discussion Thread!
Actually if you look at the CGI Grievous in Episode III and the Grievous introduced in the Tartakovsky microseries around the same time, Grievous would probably be even larger and taller compared to humanoid figures. To be frank I've always felt that most of his 3.75" action figures since 2005 have been a little on the small side and that they haven't really nailed his proper dimensions in that scale, but the overall likenesses have been close enough or even spot-on so the size issue doesn't matter as much most of the time.
Human instinct is pretty strong. You can't expect us to change overnight.
