The Predacon Kind.
Sorry, couldn't resist.
Open it all, collect a lot almost to the point of completionist, but draw the line at packaging variants and certain repaints of too many bb's damn it Hasbro!
Here we shall break it down a bit more concisely:
G1: Dream of having it all, from every single US release to all the Japanese rare and exclusive figures as well as the UK exclusive stuff and the Mexican Jumpstarters, probably not going to pursue that dream to hard though.
G2: Want it all, may in fact succeed in having it all someday.
BW: All of the American stuff, BW II and BW Neo must be mine.
BM: Complete the line, including Botcon Exclusives
RID: SO CLOSE, Just need a handful of figures and I will have it all, Brave Max also required.
Unicron Trilogy: Want all of Armada, most of Energon and all of Cybertron, will I get it all? Depends on how hard I pursue the elusive figures.
Universe 1.0/Robot Masters: Want all of RM and most of the stuff from Universe 1.0, including some of the figures I sold to make some extra spending cash.
Movieverse: All unique characters from the first movie line with a handful of repaints wanted, from RotF I'm looking at a similar endeavor, for Dark of the Moon, mostly all the unique new characters with only a few of the remade from Movie One and Two characters.
Classics: 100% Complete
Universe 2.0: 100% Complete Deluxes minus the three SE Decepticons I want, need mostly Voyagers, Ultras, Exclusive Mini-Cons and Legends.
Generations: 100% Complete Mini-Cons, close to being caught up with Deluxes, and that's about it.
Prime: I'm only looking to pick up Arcee, Airachnid if they make her, Vehicon and Zombie Vehicon, and maybe one or two others. But I'm not going to get into it as much as past lines.
PCC: Want to Have'Em All.
So yes, I am Semi-Completionist, and everything I own is loose. (Some unfortunately need to be repaired/replaced due to breakage, but that comes with the territory in toys.)
I don't collect Machine Wars, Titaniums or certain other Japanese only toylines however such as the Masterpieces and stuff, and I decided Alternators were just not for me.
