Verdict: 2/3. Not Bad.

“The important thing is not to stop questioning. Curiosity has its own reason for existing. One cannot help but be in awe when he contemplates the mysteries of eternity, of life, of the marvelous structure of reality. It is enough if one tries merely to comprehend a little of this mystery every day. Never lose a holy curiosity.”
– Albert Einstein

“I have no special talent. I am only passionately curious.”
– Albert Einstein

My Verdict: Highly Recommended. Just get it and play.
