This is a great topic. I'd have to say that at the time, almost all the POTF2 figures impressed me. After a 10 year lack of new figures, I would have taken anything (yes, I even bought all the Bend-Ems!). Although the earliest ones were a little on the beefy side, it was still cool to see some modern versions. I think the ones that have held up nicely even compared to the most current lines are:
-C-3PO (all versions)
-Yoda (I prefer this one to any of the AOTC or ROTS ones, those look a little on the angry/possessed side)
-Luke X-Wing/Snowspeeder Pilot (he's great esp. if you pretend he's someone other than Luke)
-Hammerhead (the new one is nice too, but the '96 version was perfect except for the gi-normous cannon)
-Tie Fighter Pilot (although the saga one is better, this guy is still flight-worthy)
-Emperor (I still like this one over crazy big hood)
-Death Star Gunner
-Endor Rebel (still cool since even though they've made more recent versions, this one's like having a variant)
-Muftak and Kabe
-Jabba's Skiff Guards
-Rebel Pilots Cinema Scene
-Max Rebo band pairs
-Death Star Droid
-ALL the Comtech figures
....and my personal favorite of the POTF2 era, the Gammorrean Guard. That is one nice figure that I don't think they could improve much on, with the exception of some more articulation in the arms.
Sorry for such a long list, but I'm not too picky when it comes to the "little plastic men"! I know some collectors would like every figure from this era to be remade with super articulation and totally movie accurate sculpts and paint schemes, but I think these guys hold up and don't really need an updating.
Let's hear more thoughts!
