All of those consoles were thought to be the end of the PC Gaming scene of which i've been a part of since the Zork days.
PC gaming was and still is the innovator of gaming.
Here is my recollection of the PC game wars.
When the PC moved to better grahpical games on CGA and EVGA, the NES was already at its max limits.
So when the SNES came out shortly after EVGA games in the early 90's, the PC gaming industry was declared dead.
As PC's regained market share, the SONY playstation came out (1995?) and again the death of the PC gaming was declared.
PC's fought back with 3dFX, the Voodoo card. I'll never forget seeing tomb raider with that beautiful 3d glide version of the game and just thinking "how could this ever be topped"?
Then in the late 90's when PC gaming was at its near peak, the best PC game ever to come to PC's got bought by the biggest PC backing company. We thought PC's had won the war when Microsoft bought Bungie. Who would have thought that it was nearly the nail in the coffin. Between Xbox and PS2, PC gamers had a new system not only to look at but for the first time, but truly hack.
Then came NVIDIA. The PC gamer's savior. Producing the RIVA TNT, PC gamers finally were revived. This led to 10 years of very expensive graphic cards where PC gamers would briefly lose their edge while a new console like the PS3 or 360 took the lead. The fight still goes on, although the PC is now clearly in the drivers seat, behind ridiculous video cards like Geforce 400 series. PC gaming is 7 or 8 generations ahead of the best consoles out there. But i'll admit, i play now 50% of my games on the PS3/360. But when i want to be fully immersed and get lost, nothing beats playing a game on a high end gaming rig with a supersharp large monitor 2 feet from your eyes.
