One day I got curious and what to find out the exact size of the Mass Effect global fanbase.

North America=2.98
Europe=1.85
Japan=0.06
Rest of the world=0.56
So why do you think Mass Effect is more popular in North America and Europe? Cultural reasons? Is spaceship adventure more appealing to Western people? Economic? People in other parts of the world can't afford AAA console and PC games?
