The most impressive thing I find is Sony's penetration during the PSX era, outselling the previous home console market presence by a factor of two!
The next most impressive thing in the data is how Nintendo, after only having sold a maximum of 8M home console units in Europe in gens 3 to 6, managed to really make a killing in gen7 with 31M units sold!
And of course, Sony's 52M in gen6 is a serious record! Will be very hard to beat, and destroyed the SNES era.
