Transformers and Star Wars really are about it for me, although in the past I also collected Spawn and McFarlane Sports.(Still do if one count exclusively buying only Minnesota Twins figures)
I also have a select bunch of wrestling figures collected over the years. I don't like the WWE figures that much, and have just bought the old WCW figures and newer TNA figures of my favorite wrestlers.
Oh, yeah PetShops and Pokemon too for my daughter......
1. Transformers (who am I kidding, it is number one)
2. DC Universe Classics. Truely one of the best toylines that I have come across. However, the god aweful distribution is going to kill it.
3. G.I. Joe. I`m focusing mainly on Cobra myself, but the rest of the line looks pretty good.
4. Spider-man related stuff
5. TMNT. I only have the four turtles and still want to find Splinter to finish off my core set.
6. DC Direct Green Latern Line. Cannot wait for the Blackest Night series 1 and 2.
