I may be a biased Genesis Kid, but SEGA was always ahead of its time.
To me it still holds as one of the coolest technologies (aside from a computer of course) from my childhood. Managed through tv channel sideband data.
NEC made some good looking console hardware for the Japanese market too.
R.I.P. Dreamcast, R.I.P. 32x, R.I.P. Mega CD, R.I.P. Saturn...
A technical demo like Bleemcast doesn’t demonstrate how far ahead something is, it has to be seen relative to the hardware of a similar generation. Having said that the PS2 which had some early programming hiccups would go on to eat DC’s lunch.
