Quote - After all, a car with a 50 HP engine will never be able to outrun a car with a 1000 HP engine, no matter how well designed it is.

I would like to see the face of the guy in his Audi when the light opens and my wife with her small car left him 100 meters behind.
I do the same, but she is a woman....
It's not a question how much something is powerful, it's a question how it is used.
You cannot compare computers with game machines, their design are very different.
Computers are general use machines, game machines are designed only to play games.
Game machines lack of the resources that computers have, but have a special hardware designed specifically for the task that makes them far superior for playing games.
You cannot compare a pinball machine to a PC, they don't use the top line Intel 64 bit quadcore, have no 250GB SATA drive, but their hardware is amazing in technical sophistication.
Even for 3D applications PC are not designed for this task, it lack of many resources, so any dedicated hardware will give far superior rendering performance and resources.

Quote - 43.0% 18–49 years

That's the problem with statistics, you cannot put 18 years old in the same group with who has 49 years.
At the age of 18 he/she is young, he is in school, probably not working and full of free time.
At the age of 35 he /she is adult, married, with children, working in a job , taking care of the family and very little time left free for playing games.
Games are very time consuming, I love RPG games, but they take a long time, so when I start playing a game I don't do anything else for some weeks!!!....
Not any adult person can do this. - Where is employee Joe? - He is at home playing games!

Stupidity also evolves!
