The fiction and characters are mostly my primary motivator to collect the toys.

So far the only fiction that I have enjoyed enough to get me to buy the toys are G1 and Beast Wars. As a result I buy toys from those lines or directly related (Classics, Binaltech, MP, etc).

Even though I did not like the Animation style chosen, I had hoped that Animated would be a third fictional linw that I would collect from but that didn't happen.
