America has more than 3% of people that can't afford a video game system so that's bullshit. The study says 97% of kids play games. The question asked was probably; "Have you ever played a video game?" and the moment the kid says yes he is a video gamer in the eyes of the survey. That's like asking people over 21 if they had ever had a drink and then saying 97% of Adults drink alcohol. It's a stupid study and it's inaccurate.
If it's your first time, I would recommend buying a PC and then adding and replacing parts over time, doing it all at once for the first time can be overwhelming, especially because a lot of people forget the little things like a power source.
Frontlines: Fuel of War had a 44 player cap on 360 and even then, no one played Frontlines, I rented it and could not even get in a game. No one plays that game at this point. Anyway I have three beautifully silly words for you:
Massive Action Game
So there, I just told Frontlines: Fuel of War. I like the Idea of 8 player Co-op, it's just too ridiculous to work.
