Whats the top TF lines do you collect and what make you collecting still? What keep the fire inside you that makes keep buying more? I go first...my top lines that I collect are G1, "Classics", and MP lines. The reason why I keep collection because I grew up watching G1 TFs back when I was a kid (G1 is my fav. cartoon)... I guess I'm a kid at heart. The classic and MP line are the main reason why I keep buying. If it wasn't for those 2 lines I would only be collection G1s.
