I can sympathize with this point of view. I like exploring an all new game myself. However, games are expensive enough that I don't want to risk spending money on a loser (not that FFG has many of those).
Normally I'd agree, but I figure since I'll be likely be receiving it as a Christmas present (it's now at the top of the wishlist I gave my girlfriend) rather than purchasing it myself, I won't have any buyer's remorse. It'll also give the gift more of a special feeling if I don't already know everything about it inside-and-out.
Besides, in Kevin Wilson I Trust.
