Yeah, I was just thinking the other day about how much improvement there was to videogames between 1993 and 1998. We went from 16 bit sidescrollers on SNES to Half Life in those 5 years.
Meanwhile, there hasn't really been much graphical improvement to 3D engines since Crysis, which came out in 2007. That's 11 years without much progress to show for it.
Those were the days...
