merlocka is right.
The game developers must cater towards the people with lower end systems. If the game developers make awesome games that take full advantage of the GF3, that would mean it would run like a pile of dog poopoo on Rage128 or TNT cards or it might not run at all. If it does not run at all, the game developer just isolated a largely potential group of gamers who have a Rage128 and the similar.
That would translate to weaker sales (not because the game is crappy, but because alot of people just simply can't run it).
Don't worry though. As people with weaker systems play today's games (eg RTCW, Max Payne). They'll be forced to lower the detail settings or else it would be almost unplayable due to low framerates. However, this is what drives the gamers into buying better hardware. JoeGamer might go "OMG THIS GAME RUNS LIKE SHIET CUZ MY SYSTEM SUCKS!" Okay...so now he'll have that desire to go out and upgrade his system. JoeGamer now upgrades his system to the latest hardware. JoeGamer's dollar just helped out the economy since it helped pay for someone at Nvidia or AMD's paycheck.
Also now that JoeGamer has the latest hardware, this trend of upgrading will also be seen in other gamers too. So in a few years when we see a GeForce5 or what not, game developers can now start to utilize the hardware seen in GeForce1,2,3 since the lower end gamers have now upgraded to at least decent hardware. This has been the trend seen throughout the past few years.
My point is:
- If game developers were to make a game just for GF3 owners, then they'd lose profit. They'd also hurt the economy because they would be forced to lay off workers due to the lost profit.
- Time is the key to better games. Hardware technology is accelerating fast but the people's hardware isn't being upgraded at that kind of pace. Game devleopers have to let them catch up. But for the game developers to actually stay in the business for another few years, they have to find a way to make money. To make money, they would make games that cater to the most largest possible gaming populous.
