I wasn't too sure about this at first, my main problem is that the DS screen is so small that it's hard to fit a lot of text on to it, even at the smallest possible font size. This means having to flick on to the next page every couple of seconds and I found it really hard to get as engrossed in the book as I would do with a normal paper book. However, I stuck with it and got used to it and by the time I was coming to the end of my first book I was completely hooked and couldn't put it down!!
The choice of books on this game is a little bit random. For example there are two Sherlock Holmes books, but they are not the first two books of the series, they are from some other random spot in the series
Somebody asked another reviewer if there was a dictionary - in fact there is! I have only read Tom Sawyer so far and yes there was a dictionary - but it only had two entries for the entire book!!
The DS works very well as a reader, the backlight is at a perfect level, it's easy to turn the pages, go back to the main menu, go to a different book or do whatever you want to do. If you close the DS, you are at exactly the same place when you open it. If you turn it off, it asks you if you want to go to your previous location when you turn it on again. You also have the option of placing bookmarks.
So although I'm not 100% happy with the choice of book in this collection, as an experiment to see if the DS can be used as a reader, tha answer is a resounding YES. I look forward to more collections coming out!!
