it was games that pushed computers into the home market in the first place.
if there were no games a computer in the (average) home would be an impossible dream. my grandma definately wouldnt have one.
atari, commodre, etc.
the first pcs were bought so people could by games.
games push harware limits, so the hardware industry uses its profits from lots of users to make new hardware, which again (and looping forever) is made redundant.
look at video cards. office and destop stuff does not need such gpu power. games do. that is why there is such rapid development in the video card industry. not too long ago my 9600XT was a pretty cool mid range card. but it will be absolutely blow away by the gforce 6.
if it wasnt for games the big iron servers might only now be getting into the MHz, let alone GHz computers at home....
but just because you have the best platform for games doesnt mean you will survive... my trusty amiga didnt.
going from real sound to pc speaker was a horrible experience
so if you could influence the games companies to port games to your system (think playstation) and then out market your competition (think playstation) you have a successful product (think playstation).
N64 was 64 bit compared to PS 32, dreamcast was a much better machine.
the only thing that saved nintendo (they should have died after the game cube) was/is the gameboy, but now nokia and sony are trying to cut that grass.
sega are still alive because they make cool games.
its that G word again...
the driving force behind the computer industry.
