If you haven't picked up Angry Birds Space because you think "it's just another Angry Birds game", you're sorely mistaken - this game's outer space physics adds a whole new dimension to the franchise.
The new gravity mechanic is easily the most interesting addition to Angry Birds Space, allowing for much more inventive level design. ... I have to admit it's pretty entertaining to just barely nudge a weightless pig, subsequently watching him get sucked into a planet's gravity well and lazily sail to his death.
Angry Birds Space is the exact shot in the arm the series needed. Anyone burnt out on vanilla bird flinging will enjoy the game's out-of-this-world adventure.
There is real craft on show in Angry Birds Space ... beneath all the Angry Birds As Phenomenon noise lurks a genuinely excellent game, whose success has been built on quality, not just hype.
So why is this a huge risk? It's different. Very different.
