I remember scraping together the money to buy a 486/66 just to play Duke Nukem 3d, and then the moment I got a look at Quake (required a P75?), realizing another upgrade was in store.
So many awesome memories of gaming in the 90s...voodoo rush to voodoo2, seeing glquake and then Unreal run for the first time (jaw dropping, in both cases). Everyone coming up with patches that added glide support. Walking into computer city and seeing the huge stack of Starcraft boxes. That wacky assed spaceorb.
Gaming felt different back then...less of a focus on the megapublisher and their latest hit, and more of trying to actually make a decent game that pushed the limits of hardware.
