The 3.75" scale is my favorite and most collected format. I don't have a lot of vintage aged lines from my collecting heyday left but I do have some figures from the Crystar line and all twelve figures from the Star Trek TMP line and I am needing a complete Thallo to have the Clash Of The Titans line done minus the Kraken, which I will probably never own. Modern 3.75" lines I collect are things like Star Wars, Indiana Jones, Twilight Zone, and various other sci fi/fantasy stuff for the most part.
