I find a lot of my favorites are from the earlier sets, the newer ones being full of sculpts that look like rejects from some freakish cartoon. Of course, the early sets had their share of stinkers as well and some of the newer minis are pretty cool, but nowadays I am content with just picking up a handful of commons/uncommons per set.
cheers
I count seven (Bugbear, Bugbear Footpad, Bugbear Champion of Erythnul, Blood Ghost Berserker, Bugbear Gang Leader, Bugbear Headreaver and Bugbear Lancebreaker)When you're getting the sixth or seventh (or whatever) bugbear sculpt, you know they're running out of ideas.
