Too many. Back in the 80s my father got a new PC from his university. It's a brand new IBM-PC compatible with two floppies, no HD, a turbo button and a turn-key lock. Fast forward 10 years, in 1993 we got a new 486 machine and we installed Windows 95 a couple of years later using tons of floppies. Fast forward another 3 years we finally got a new Pentium with perhaps 16MB of RAM and a CD driver. I played first modern game Duke Nukem 3d on that gig and still remember that quiet night. I'll probably remember it till my death. In a few years we got another machine with maybe 32MB of RAM and I started to play every FPS I can find. I found out about Worldcraft and started to make some levels. Unfortunately this did not turn into a career. I still regret that I didn't push on because I was probably one of the first group of players in my country that actually do any level design. Now everything above becomes history. Along with it cassette player, CD player, pocket pet, mp3 player, DVD player, etc. Tech moves so fast.
