Rabbids Lab is a novel idea that works really well as part of Rabbids Go Home – it provides a nice distraction to the main game and compliments its zaniness. Releasing it on its own, however, just leaves you with an underwhelming application that will be very short lived. Visually, the production values are lovely and the audible bwargs of the Rabbid are equally amusing, but the Rabbids Lab just doesn't meet the cut as a standalone download.
If you love the Rabbids that much, you should already have the game. Purchase this knowing that all you'll be getting is a glorified dress-up game without the ability to save or share your creations in any real sense.
