Roman5: I had the exact opposite experience
All of my gaming that was done growing up was done only on PC
now that I'm 22 I'm playing many many console titles that I have missed out on, MEGADRIVE, PS1/2, NES/SNES, NEO-GEO etc
What I really love about older consoles is that they often offered much different great experiences than the PC and that's what set them apart, while nowadays they try too hard to BE a PC instead of just a dedicated game console
That is exactly what is happening today. Publishers try to bring gameplay experience from a pc to consoles but this just doesn't work. They should build on the strengths of a console instead of for example to do FPS on a console instead of a plattformer that has good gameplay on a console.
PC gaming is indeed very different to a console in more aspects than just control with KB+mouse. You can also concentrate way better on small details on a pc in contrast to a TV screen. Most noticeable in FPS and RTS. Even if you would play a console with KB+mouse the gameplay would be different. When you see today that many games on XBOX and PS3 are FPS which have poor gameplay it really makes you think hmmm are customers really that dumb ?
