I do try and push things along when there is a review, so a more leisurely play through would probably be a couple of extra hours. Rebecca didn't get time to admire the surroundings, she just ploughed on!
This isn't a difficult game so she was able to maintain a furious pace, helped here and there by some hotspot reveals.
I failed to mention the map in the review. It helps you get around, and will flash when a new location is added.
Quantity has a quality all of its own
