I'm not a huge fan of Star Wars figures. I'm not really that into the expanded universe, the figures ussually have questionable articulation, and I still have bad feelings about some of my purchases back in the 90's. But they're in 3.75" scale (for the most part) and I do like that scale for toys.
When I saw the IG-86 figure and how many joints it had, I thought to myself, I should get that. And I'm glad I did, the thing's like a fricking Chinese Acrobat. (I'm Chinese, it's not as racist a statement as you might think.)
Also, due to the hole in its back for the gun backpack, IG-86 is one of the few non GI Joe 3.75" figures that can wear a GI Joe jet pack.
