Yes, my parents spoiled me, but most of my collection was bought during my supposed "adult" years. I lost a bit of my original bots and didn't start collecting again until Beast Machines, so one could imagine the work I've had to put in to go back and nearly complete Beast Wars.
I collect mostly American Transformers, because I enjoy personally hunting down bots more than I do ordering them over the internet. Also, in my experience, the American versions of most toys are made with better quality than their competitors (although I'm not sure why that is). So, yeah. I'm waiting on Cybertron. I'm not jumping the gun and ordering Galaxy Force. Collections are better created with patience, I think. I do like certain Japanese Tf's and I track them down from time to time.
Let's see.... what other questions? Oh yes. I "think" I have a decent job. I work for the government, so that affords me a pretty decent collection. There are far far better collections than mine out there. I just happen to have a decent display setup for mine. Everyone has a different living situation, so it's difficult to compare collections and such. I don't spend much time worrying about it.
I dedicated that entire room to nothing but Transformers. A lot of people can't do that and it's understandable. It's just me and my wife and we have a decent sized house, so I was able to do that. I don't plan on having any kids (atleast for the moment), so it's not like I'd need the room for something else.
We don't concentrate on just Transformers. I could put pics up of other rooms where we have other collections. The kitchen will one day be dedicated to my wife's collection of Strawberry Shortcake. She has most of her original dolls as well as damn near everything from the current line. We have also spent a fair amount of time on our Justice League (Unlimited) collection, which we have every figure, minus a rare varient "white faced" Doomsday.
I picked red for the room, because I wanted a bright "eye catching" look. I wanted the room to jump out at people. I think it does. Plus, the red goes with so much that I have in there. Besides, it's a Transformers room and obviously, I'm more of an Autobot/Maximal fan. Hence, the red.
As far as numbers go, I haven't ever counted them. I wouldn't know where to begin. Do you count each Minicon or as a team? Here's something that would help if I did...
My rough estimate as I'm not even at home:
Generation 1... Probably somewhere around 50% ?!? Who knows?
Generation 2... Definitely 60%+.
Machine Wars... 100%+.
Beast Wars... 85% I would guess, maybe more.
Beast Machines... 99% I lack that stupid Target exclusive Magmatron to be complete (although I have the Japanese one.)
Walmart Dinobots... 100%.
Robots in Disguise... 100%+.
Armada... 100%+ "Red Thrust" and now Micron Rampage and a couple of Micron minicon teams.
Energon... 100%+.
Universe... 100%.
Cybertron... 98%. Looking for Shadow Minicons and Hightail.
Alternators... 98%. Looking for Rumble and Ravage II.
Binaltech... Only yellow Tracks.
TRU exclusive reissues... 100%.
Convention exclusives... All I can say is I have a fair amount of those.
MyClones... 100% Without any of the chase pieces.
Beast Wars Microverse... 100%.
Transformers Choro Q...100%? I dunno. I have 6 different ones. Are there more?
Heroes of Cybertron... 100%+.
Built to Rule... 100%.
Japanese Beast Wars... 70%+.
Classics... Rodimus, Bumblebee, Astrotrain, Starscream, Megatron, Optimus Prime are in the bag.
Titaniums... Looking for 3" Grimlock, Predaking, and Scorponok, as well as 6" Optimal Optimus and Scourge.
Attacktix... See Attacktix thread.
I don't have a lot of the stuff other people have such as much Galaxy Force, Japanese Generation 1, much Micron, Binaltech, much Superlink, etc... That just hasn't been my thing thus far.
I have a hell of a lot of TF merchandise and I really enjoy that collection as well, no matter how cheesy the stuff is *cough*Transformer watches*cough*. Anyway... enjoy.
