I just pick games I like, whether they be "original" or "creative" or not. Fallout was already taken, but with Fallout 2 on board, I'm just as happy as I like the sequel just as much as the original.
Everyone has their own drafting style. Poxy, Ludwig and billylove, for example, are taking games that pioneered their genres. Kirby is taking coin-up classics and Dan is reminescing about killer games that colored his stay in Japan.
Others just take the best game that they like that is available. Remember, with 10 rounds and over 300 games to be drafted, everyone's list is bound to have a few sequels or similar titles. It's the quality over 10 rounds of drafting that counts in the end.
