"The game really does require some playtime to fully get it. I understand you expected more of it, though the developers never said the game was completely based on choices, but that was the general idea. Of course the ENTIRE game isn't choice but most got the idea."
The gameplay problem isn't expecting more as much as expecting less, cutting the control fluff in this case.
As for the story, I could handle some railroading, just be honest about it. This isn't the first game where loads of choices are promised and the choices are less than the hyperbole implied.
A flashy-first game is awesome when it comes out. A great-first game is awesome forever.
