I'm merely interested in this game, so I've no problem waiting a year if need be. Enthusiasm is another level, that was the reason I pre-ordered Civ V (yeah, big mistake that turned out to be, heh).
While you're not going to get a review made by a clone of yourself, you can use the varied criticism to predict how you'll enjoy it by sifting through the praise/complaints (AP had good reviews for story and the consequences, for example). LPs are even better for this purpose, at least for shooters and adventure games in my experience. So, it is worth your time not making an emotional or impulse buy and waiting for feedback, rather than gamble $60. It's not even that long a wait, if you're some fanboy of the game and HAVE to have it, feedback for well pimped games is available pretty quickly, maybe give it a week or two. Not going to kill you.
So far I've done that with NV and DOW2 Ret, both I was tempted to pre-order but decided to just wait for reviews here and elsewhere (the latter was elsewhere because you all suck ).
