This was my third 3DS title that I have purchased, and needless to say as a huge fan of the Pokemon franchise I haven't been disappointed. Parents beware, if you are interested in buying this to keep your little precious(es) quiet you should know that this is not like the usual RPG (adventure) styley games that Pokemon is famous for e.g. Black and White/Heart Gold and Soul Silver; this is a light-hearted cutesy spin-off game in which you play as toy Pokemon which involves a lot of A and B button mashing and less strategy than the traditionals.
The best thing that I have found about this game is how long it is! Having clocked up nearly 100 hours of gameplay, I still haven't befriended (caught) all of the Pokemon in the game; as Super Pokemon Rumble/Pokemon Rumble Blast features all of the Pokemon including the few that have different formes up until Black and White 1. However, this longetivity may not be the case for younger players (or people that aren't Pokemon-Catching-Perfectionists such as myself, est. 2000), as they may become bored with the repetitiveness of having to go through the same levels again and again due to the fact that the ability of "befriending" other toy Pokemon appears to be at random, or the success of a random hit that makes them dizzy.
In short, if you or your children are a huge Pokemon fan and/or the thought of the seriousness of Skyrim turns your stomach then this light but fun game may be for you! :).
