I've gotta say this thread reminds me a lot of when I was a kid and my parents said "you're too old for toys so we're going to give them to..., you can keep a couple of them only", but my choice would be pretty much the same! For my 10th birthday I got Optimus Prime and went through this sequence , , . He remains my sentimental collection favourite (still in his box, although he's in a well loved/played with condition). Optimus comes with me, the rest proceed to oblivion.
