Vintage Gammie was one I just never owned... I think I had something against him because he was portly maybe. Same with the fat old guy that was the "Boss" character in the Fisher Price Adventure People TV crew... that guy got the shaft. Boss Hog did too.
I loved how they re-used the Gammie for Friar Tuck too... What a completely punch in the nuts to the guy who played him. His big furry underwear, his multiple knees like fat chins. It's really funny looking.
Seriously though, I don't know why I never owned a Gammorrean from the Vintage days other than I probably wasn't as into SW figures and was drifting towards GI JOe... the original was a pretty great sculpt though, and the fist hand fit the figure well because he just looked like he'd be punching people instead of using technology, for some reason. The big archaic axes and furs I guess gave that impression even though others had force pikes and pistols. I guess I never noticed those details as a kid.
The new figure is really a work of art though... I'm not sure I'd put him as #1 though. I don't even know for sure he'd make my top 5 figures. I think VOTC/EB Chewbacca, Hermi Odle/Ephant Mon... They're above the new Gammie. He's definitely good though. Top 10 for sure, and probably a big away from the 10th spot.
My gripes are pretty much what others note... His helmet falls off him far too easily, his skirt isn't quite right and needs modified to be perfect looking, and I'm a little miffed that they inhibited his leg articulation for no real legit reason up near the thigh joint. It's not too bad, but having the guard sit is not going to happen.
One other thing I'd have dug if they'd have done it (though it's nothing that shaped my opinion at all, just would've been neat), is that his jaw was ripe for articulation. It's designed in just a way that it could easily work without showing at all. It would've been neat... not necessary, but at $9 a pop it would've been appreciated.
The only real gripe then at the end is the availability which Hasbro I believe said they intentionally shorted Wave 3 shipments to retail... I think the Gammorrean would level off though, if enough got out at retail. I think Hasbro sees this figure's popularity and I wholely expect to see more of it out at some point.
