I'll start of by saying, if it isn't obvious, this is not a game.
I guess for most DS owners, this won't appeal. There's no gameplay at all, and applications like this can annoy a lot of people.
But, I love it. This one, tiny cartridge contains 100 books, the 100 books you NEED to read but never have, or at least I haven't. This game is a great opportunity for me to finally read them.
It's very easy to use. You choose how you're 'handed' and then hold the DS like a book, like in Brain Training. If you are right handed, you hold it the normal Brain Training way, and if you're left, the left handed Brain Training way.
Obvious.
The DS shows a shelf of books, spanning over both screens which you con scroll through using either the stylus or the d-pad (or the A/X/Y/B buttons depending which hand you use). All you have to do is tap a book to pull it off the shelf and read.
You can read information on the author, on the book itself, or just get straight into it. You read it like a book, using the stylus to turn the page bysliding it in the direction you want to turn.
If you don't want to use a stylus for some odd reason, you can use the control pad. Depending on which way you hold the DS, the D-pad or lettered buttons turn the pages, though you can also set the L and R buttons to turn it.
You can program pretty much any button configuration, and use any button you want to turn pages.
100 Classic Books also contains one other feature that, while not importaant, is a very great addition. This is the music. It contains a few different choices of relaxing, easy listening music to use whilst reading.
100 Classic Books DS is brilliant, simple as. It's easily portable, soyou can read it anywhere. It's simple to use, you can just pick it up and read it for a bit whilst waiting.
It's easy to stop as well. You can set three bookmarks in each book, so you can pick up where you left off within seconds, no fiddling needed. Just tap the screen.
No, it's not a game, there's no unlockable stuff (unless you count the extra 10 downloadable books) and no 'replay value' but it's definetly the best cart to grace my DS yet.
With 100 books, 100 Classic Books will last you pretty much forever, and at the bargain price it is, it's too good not to buy.
