I find the cultural differences in the video game market quite interesting and will to share some of my observation and here what you have to think. 
If we look at the console war we see Nintendo killing it with approx. 77 million and the 360 and PS3 at 46 and 42 respectively , but the breakdown is the interesting part. The Wii is the only console that is split evenly, considering the population of each district, while the 360 is most sold in the US at 27 million compared to the 17 million PS3 sold. While in the EMEA, look it up, the PS3 has sold 20 million compared to the 18 million 360s. And Japan is so skewed I am not dealing with it.  Racing games generally sell better on the PS3, GT5 sell 2.9 million in 2 weeks compared to Forza 3 selling 614 hundred thousand in the same period. 
Or NFS: HP selling 634 hundred thousand on the PS3 so far compared to the 587 hundred thousand on the 360. Non console exclusive shooters tend to sell 1.5 times as more on the 360 than PS3, ex. MW2 sold 12 mil 360 and 8.8 mil PS3, BLOPS sold 8 mil 360 and 5.5 mil PS3. Action adventure games tend to sell about even, ex. AC:B sold 1.72 mi on the 360 to the 1.70 on the PS3. 
I am currently very sleepy and hoped you enjoyed this. If people like this I might do something again in the future similar to this, or just expand to the differences.  
Your friendly and sleepy  neighbor.
