Ah, it's only sad and cynical people who never pre-order.

So far, though, my rule of 'never pre-order' has stood me in good stead. I really, really wanted to pre-order Aliens: Colonial Marines. I mean, an Aliens game! With the iconic pulse rifle and everything! What could go wrong? Buuut... well, I'm a sad and cynical man, who's seen enough people complaining bitterly about their mistakes, and I couldn't help noticing the rather worried and reserved tone of the previews... and to my enduring regret my cynicism was proved right.
I am quietly confident I'll buy FO4, but I'll do so knowing what I'm getting - deep RPG, sprawling action adventure, or messy bug-fest (yeah, might wait for a few patches if that's the case).
I don't think Bethesda are overhyping FO4, but the fans and the journalists most certainly are. It may be a brilliant game of its type, but there's so little information out there that it's hard to be sure what that type is
