Yeah, I think half the fun of these speedruns is the fact you know the game, you know how you played it and therefore can be impressed when someone comes along and does it fast. I never owned a console until the 360 as I was a C64/Amiga/PC boy so all those NES/PS1 titles they run at SGDQ doesn't do anything for me at all.
Plus the fact that we are almost on the same time zone as ESA in Sweden means the best games are shown in the evening rather than 2am in the morning.
