The original comment said they took their family to Burger King and then you made up that they had it delivered and that was why it cost what it did.
I'm not sure why you decided to make that up when it didn't fit the comment, nor why you expected a full itemized list in a copy to price compare against, but ok.
Honestly it was just a good game. I saw it attracting both Potterheads and non-Potterheads. (I would not consider myself a Potterhead).
Does it have a bunch of replay value? Not really (neither do a lot of games). But man, that initial playthrough was just really good. It also looks like I clocked 113 hours on the game, so that's a pretty decent return to me.
Also, despite the source material and the author, it had a lot of very inclusive elements, which were a nice touch.
