I want to get excited for fallout 4
but then again I don't want to get too excited for something that could be a flop
I don't think bethesda can afford for this game to be a flop. Fallout and TES are their bread and butter, and if the really, seriously forgeted up their main course I'm not sure if they could even feasibly recover from that. I'm confidant that Bethesda wouldn't let it fail, even if it meant delaying it or something else similarly drastic.
All the same, I'm not going to preorder it in case I find out that it performs poorly or does by some incredible means fail.
