Estimate Playing Duration

How long will the average player need to complete the story line?
How big a part will collectables play?
I'm thinking that 40€ might be a rather high price, if the story won't be longer than 10 hours.

I believe that the game should be at the very least fifteen to twenty hours similar to other roleplaying games.
