It’s difficult to put ones finger on what is exactly different between PC gaming now and 15 years ago. Aside from the obvious differences common to all platforms; the technology, graphics, sound and hardware etc were older – but there was something more exciting about gaming back then.
It felt like PC gaming was evolving monthly, compared to now when PC gaming is very much dorment thanks to the consoles taking over the world.
Between 1995-1998 we went through 6 different version of Directx, probably a hundred different models of soundblaster and various Voodoo / 3dfx graphics cards. The technology evolved so quickly, you couldn’t keep up.
