If you'v seen my pas comments you'll know that I'm a huuuge astronomy geek. I wanted to go to space as a kid. So far there hasn't been any luck. Little experiences like SpaceWalker are the ones people like me are left with. I love the features like

Steer your spacecraft to witness the hyper-realistic scenery of the solar system
Experience the celestial bodies orbiting around the sun in full angle
Empower yourselves with the knowledge you learn on each planet
Jump through the wormhole and become the superhero of the space
Collect “Lost Teddy Bears” to complete challenges to protect the universe

I prefer they stuck with more "Hard Science" stuff and keep it closer to a simulation. St least they are creating some interest in space which is getting overlooked due to all the apps and mobile phones.
