There is also a driving game called Blocky Roads available as an app. It's basically a complete Rip off of minecraft but a shit driving game as well.
The kids absolutely love it <shrugs>
My 6 year old is addicted to it. It's Lego on a computer essentially. It's a cheaper alternative to actually buying and playing Lego with your children.
Currently, the over priced minecraft torch purchased from Amazon is Lost. Crisis doesn't even cover the reaction.
