1. Collect all American G1 figures, loose and complete in good condition.
2. Collect all G1 Japanese and European exclusive figures loose or MIB, complete with paperwork.
Like American G1, this includes tech cards and boxes when possible. An exclusive is defined as any mold that was not released in America, or any figure that was recolored for Japan or Europe. For example Minerva would qualify, Cab would not since he was not repainted from Hosehead. Again, no re-issues or KO's allowed.
3. Collect AFA American G1 of figures owned as a child.
4. Collect all American G2 and Beast Wars figures loose and complete in good condition.
This includes variants (Black & White Prowl), exclusives (Wal-Mart Rattrap), and Botcon figures from 1994 to 2002.
5. Collect Japanese Beast Wars and Beast Wars II exclusive figures loose or MIB, complete with paperwork. Collect all of Beast Wars Neo, MIB.
Just like the Japanese/Euro G1, an exclusive is defined as any mold that was not released in America, or any figure that was recolored for the Japanese lines.
6. Collect all Japanese Car Robots figures, MIB.
7. Collect every color SCF from ACT 1 to ACT 8, including chase figures and exclusives.
Just like it says, every color SCF from the Generation One period of SCF, including all exclusive sets, Wonderfest, Figure King Skywarp. All of it. No HOC allowed by any means.
8. Collect all e-Hobby recolors of G1 figures, MIB, with exceptions.
This one is a little tricky since E-hobby tends to be all over the place. But my basic rule for this is if it was released by E-hobby and is a recolor of an existing G1 toy and it would fit in the G1 universe then it is allowed. So I won't collect the MP Ghost Starscream because it isn't a G1 mold and I won't collect the VSE set because it wouldn't fit in the G1 universe since it is Shattered Glass. This is a newer area I have ventured into so I haven't worked on the rules for long with this one.
9. Collect at least one of each "Animated" character, best possible scale. Loose and complete.
10. Collect all Masterpiece figures that appeared on Seasons 1-3 of the G1 show that are in scale to each other.
You may have noticed a pattern forming: I need to keep adding qualifiers in order to substantially cut down on the figures in the line. So for the MP figures, Soundblaster doesn't qualify but Ratbat does. Megatron doesn't qualify because he is out of scale with the MP-10 figures and beyond. Tigertrack also doesn't qualify but I bought one anyway because I love yellow Lambos and he isn't displayed with my other figures anyway.
11. Collect Classics, Generations, Universe, Henkei and Third Party figures that will be used to create "scenes" from IDW comics.
This one is all over the place. Because CHUG (as may people call it) and Third Party figures are so sporadic and come from so many different lines it is hard to set some rules down for them. But I have decided the best way to collect and display these figures is to purchase ones that would fit well together in the IDW universe. So I have Toyworld's Hardbone (Hardhead) with Classics Optimus Prime and Legends Wheelie since they are together in RID. I have a majority of the Lost Light crew together on another shelf. I have Thrilling 30 Metroplex with Toyworld's Throttlebots and Hexatron to represent Spotlight: Metroplex. This is more or less a collect what you like and don't what you don't rule, but I at least have a basic framework in mind when purchasing figures.
12. Collect all the minicons not released with larger figures.
13. Collect anything Sharkticon related.
I love Sharkticons, my wife loves Sharkticons. This is the only character collection rule I have. Whereas some people collect all Starscreams or Optimii, I collect all Sharkticons.
14. For everything else, collect what you like and don't buy what you don't.
This is probably my most important rule, as it completely destroys any semblance of completionism that I once had. I once thought I needed to own everything, but after the Unicron Trilogy and the Movie figures that is no longer true. This rule gives me freedom if nothing else.
15. Display and curate everything in the most aesthetically pleasing way possible.
So there they are, the 15 rules that govern what I buy and what I don't. I feel they are pretty all-encompassing, at least until the next Transformers line comes out. Now I just need to remember to check back on this thing every now and again to make sure I'm not violating anything.
