Overall there is a great roster of games for the 3DS of all kind of styles. A few areas such as the horror/thriller and strategy sections are lacking a bit so far but soon enough there will be games such as Monster Hunter, Fire Emblem, Dragon Quest, Super Smash Bros, Pokemon and many more to add to the system's so far very good library.
