Don't forget that when Larian moved the release date up, it gave outlets roughly 4 days to play through the game, write up a review for it and have the embargo for reviews lifted on the day of release. There is really no good reason why IGN can claim to have played through the whole game, but still have to put out an article days after release about bugs and the unfinished Act 3.

While the endings thing is whatever, the choice and consequence was absolutely marketing hyperbole. Act 1 is replayable. The entire game get's very samey real quick and you can savescum the last hour to literally see all the endings.
