Ah, saw the screens in gameinformer. This all but assures me it will be GOTY... except for the choice of the little sister being an excort mission >>
They showed a really bad part for their first reveal. It's going to make everybody think that the whole game is going to be "kill big daddy to steal little sister, get little sister, make little sister steal adam, defend from assault, rinse/repeat". Spoiler
I was hoping for a bit of a scenery change with the same mechanics but oh well, don't fix what isn't broken.
Even in the gameinformer issue that's what it sounded like. Gameplay looks good but without a story, you don't have much of a game.
