Well, Evil-Lyn and Faker were almost mortal locks since they're basically straight-up repaints (minus Lyn's head piece), but the addition of Man-at-Arms is a nice surprise, as I figured he'd be put off to a later wave. We just need a Mer-Man, Stratos, & Zodac to complete the 1982 line.
I'm a little surprised that this hasn't expended into a small line of vehicles by now. Outside of the alien, I think the MOTU guys have been the hit of the single-packs thusfar. And I think it would have more legs/longevity than some of the other licenses they're single-packing.
What kills me is these probuilder sets... I don't really care for the sets, but the figures are incredible. So many new fodder parts that I'm not going to buy a $50-$80 just to acquire.
